# Topic: Tensile strength

 Reference.com/Encyclopedia/Tensile strength The yield strength at 0.2% offset is determined by finding the intersection of the stress-strain curve with a line parallel to the initial slope of the curve and which intercepts the abscissa at 0.002. Tensile strength is measured in units of force per unit area. The breaking strength of a rope is specified in units of force, such as newtons, without specifying the cross-sectional area of the rope. www.reference.com /browse/wiki/Tensile_strength   (1279 words)

 Ultimate Tensile Strength A marked decrease in cross-section is called "necking." Ultimate tensile strength is often shortened to "tensile strength" or even to "the ultimate." "Ultimate strength" is sometimes used but can be misleading and, therefore, is not used in some disciplines. The yield strength is defined as the stress at which a predetermined amount of permanent deformation occurs. When yield strength is reported, the amount of offset used in the determination should be stated. www.tpub.com /doematerialsci/materialscience25.htm   (438 words)

 Mechanical Properties of Polymers Strength is a mechanical property that you should be able to relate to, but you might not know exactly what we mean by the word "strong" when we're talking about polymers. Tensile strength is important for a material that is going to be stretched or under tension. Since strength is proportional to the force needed to break the sample, and strain is measured in units of distance (the distance the sample is stretched), then strength times strain is proportional is force times distance, and as we remember from physics, force times distance is energy. www.pslc.ws /mactest/mech.htm   (2528 words)

 Tensile strength of water THE measured tensile strength of water has long been known to be significantly less than theoretical predictions and the reduced strength is normally attributed to the presence of solid impurities that serve as nucleation sites for rupture of the liquid A favourite method of measuring tensile strength is through the dynamic stressing of a liquid by an acoustic field. Such an event is termed the acoustic cavitation threshold and is a measure of the tensile strength of a liquid. www.nature.com /nature/journal/v278/n5700/abs/278148a0.html   (244 words)

 Tensile Strength Test In order to use metals in particular applications, it is sometimes necessary to know their tensile strength. This defines the yield strengths of the metal. If the yield strength is exceeded the object will be permanently deformed and likely will no longer be useful. matse1.mse.uiuc.edu /~tw/metals/e.html   (605 words)

 Rope Inc. Tensile Strength To estimate the minimum tensile strength of a new rope, reduce the approximate average by 20%. Tensile strength is the average strength of new rope under laboratory conditions. The manufacturer's recommended working load is determined by taking the tensile strength and dividing it by a factor that more accurately reflects the maximum load that should be applied to a given rope to assure a comfortable safety margin and longevity of the line. www.ropeinc.com /ropetensilestrength.html   (350 words)

 Tablet Evaluation Tests/Mechanical strength of tablets - Pharmpedia Thus, the BFI is obtained by comparing the tensile strength of tablets with a hole at their centre, which acts as a built-in stress concentration defect, with the tensile strength of tablets without a hole, both at the same relative density18,21. Where T is the tensile strength of the tablet without a hole and To, to the tensile strength of a tablet with a hole. Itiola and Pilpel21 using both granular and powdered metronidazole formulations studied the mechanical properties of the tablets and differentiated between the bond strength of the tablets as measured by their tensile strength and the tendency of the tablets to laminate or cap as measured by the brittle fracture index values. www.pharmpedia.com /Tablet_Evaluation_Tests/Mechanical_strength_of_tablets   (1645 words)

 Tensile Strength of Fine-grained Slag Concrete The advantages of this composition are the high strength [1] and increased adhesion [2] between the surface layer of the cement stone and the aggregates due to the good physico-mechanical properties of the ingredients. The latter provide the possibility of increasing the axial tensile strength of slag concrete, which is one of the important mechanical characteristics used as the basic criterion for determining the crack resistance of concrete structures. When the cubic strength is higher than 60 МРа, the tensile strength is on the average 30 % to 35 % higher than the tensile strength of ordinary concrete with natural sand and fine-grained gravel. www.ejournalnet.com /Contents/Issue_2/9/9_2002.htm   (2151 words)

 Tensile Testing Tension Testing Tensile Test Tension Test A tensile test, also known as tension test, is probably the most fundamental type of mechanical test you can perform on material. For most tensile testing of materials, you will notice that in the initial portion of the test, the relationship between the applied force, or load, and the elongation the specimen exhibits is linear. A value called "yield strength" of a material is defined as the stress applied to the material at which plastic deformation starts to occur while the material is loaded. www.instron.com /wa/applications/test_types/tension/default.aspx   (760 words)

 High tensile strength removable hose covering - Patent 4679600 The high tensile strength removable hose covering as defined in claim 2 wherein said separable closure mechanism first part and second part include means adapted to engage and secure said hose reinforcement whereby said hose reinforcement supplies hoop strength to the removable hose covering. Possible application of hose requiring high tensile strength are use of hose in deep undersea mining where the hose serves both to convey minerals recovered from the seabed and to tow a sleigh which gathers the minerals for conveyance to the surface. It is conceivable that high hoop strength is not required in the removable hose covering and in such case it is feasible to lay the hose reinforcement materials from each side of the closure mechanism without having a physical attachment of the hose reinforcement material to the closure mechanism. www.freepatentsonline.com /4679600.html   (7597 words)

 Tensile Properties Tensile tests are used to determine the modulus of elasticity, elastic limit, elongation, proportional limit, reduction in area, tensile strength, yield point, yield strength and other tensile properties. The offset yield strength is the stress corresponding to the intersection of the stress-strain curve and a line parallel to the elastic part of the curve offset by a specified strain (in the US the offset is typically 0.2% for metals and 2% for plastics). Even though the yield strength is meant to represent the exact point at which the material becomes permanently deformed, 0.2% elongation is considered to be a tolerable amount of sacrifice for the ease it creates in defining the yield strength. www.ndt-ed.org /EducationResources/CommunityCollege/Materials/Mechanical/Tensile.htm   (1988 words)

Tensile strength, the maximum tensile force per unit width developed in a test specimen at rupture or break under prescribed conditions. Tensile strength is indicative of the serviceability of many papers, films and foils, such as web printing, wrapping, bag and gummed tape, and creped papers, such as cable wrapping, tissue and toweling, which are subjected to direct tensile forces. www.testingequipments.com /tensile.htm   (270 words)

 Definition of Tensile strength   (Site not responding. Last check: 2007-11-07) The tensile strength of a material is the maximum amount of tensile stress that it can be subjected to before it breaks. Tensile strength is an important concept in engineering, especially in the fields of material science, mechanical engineering and structural engineering. In brittle materials such as rock, concrete, cast iron, glass or soil, tensile strength is negligible compared to the compressive strength and it is assumed zero for most engineering applications. www.wordiq.com /definition/Tensile_strength   (585 words)

 Engineering Stress-strain Curve The tensile strength, or ultimate tensile strength (UTS), is the maximum load divided by the original cross-sectional area of the specimen. The tensile strength is the value most often quoted from the results of a tension test; yet in reality it is a value of little fundamental significance with regard to the strength of a metal. However, because of the long practice of using the tensile strength to determine the strength of materials, it has become a very familiar property, and as such it is a very useful identification of a material in the same sense that the chemical composition serves to identify a metal or alloy. www.key-to-steel.com /Articles/Art43.htm   (1877 words)

 What is Rubber Tensile Strength? Tensile strength is the maximum tensile stress reached in stretching a test piece (either an O-ring or dumbbell). Tensile tests are used for controlling product quality and for determining the effect of chemical or thermal exposure or an elastomer. In the latter case, it is the retention of these physical properties, rather than the absolute values of the tensile stress, elongation or modulus, that is significant. www.oringsusa.com /html/tensile_strength.html   (164 words)

 Tensile Strength, Partech The tensile strength of unalloyed steels depends extensively on the C - content and structure. The relation between C - content and tensile strength of fine-blanking steels is shown in this table. If a part requires a high surface strength, it is advisable to fineblanking a low in carbon steel and to bring the part afterwards to the required strength by casehardening. www.partechfineblanking.com /design_guide/tensile_strength.htm   (106 words)

 Calculations for Snow Shear and Tensile Strength Using a Shear Frame   (Site not responding. Last check: 2007-11-07) Note: Although many researchers call this the strength to load ratio, technically load is a force (newtons), so this is really the strength to stress ratio because the units are in pascals which are the units of stress. Thus the actual strength may be different on a 38 degree slope than it is on a zero degree slope. The measured strength can always be used to calculate the strength to stress ratio on other slopes, but the issue of representativeness must always be considered. www.homepage.montana.edu /~uessc/esci450/ShearStrengthCalc.html   (1373 words)

 [No title] The tensile strength of a material may be measured in terms of either the stress necessary to cause a significant amount of plastic deformation or the maximum stress that the material can withstand. The tensile force is recorded as a function of the increase in gauge length. Once the specimens’ surfaces are finished, their tensile strength, also known as ultimate tensile strength, will be measured using a tensile tester with a minimum and maximum load capacity of five and one hundred pounds, respectively. www.sjsu.edu /faculty/selvaduray/page/mate251/SurfaceFinishandTensileStrength.doc   (1950 words)

 Stainless Steel - Mechanical Properties As engineering design calculations are frequently made on yield criterion the low yield strength of austenitic stainless steels may well mean that their design load cannot be higher than that of mild steel, despite the tensile strength being substantially higher. Spring wire has the highest tensile strength of the wire generally manufactured; it must be suitable for coiling into tension or compression springs without breaking during forming. Weaving wires are supplied in a variety of tensile strengths carefully chosen so that the finished woven screen will have adequate strength to withstand the service loads, and yet soft enough to be crimped and to be formed into the screen satisfactorily. www.azom.com /details.asp?ArticleID=1181   (816 words)
