	Stress and Strain
		Stress is a value which describes the amount of load carried by each unit of cross sectional area of a component.
		The stress that the 10,500 pound load applies to the shaft is defined as the load divided by the cross-sectional area of the shaft, which is 10,500 pounds ÷ 0.200 square inches = 52,500 pounds per square inch (psi).
		Then shear stress applied to the bolt would be 20,000 pounds divided by twice the bolt area (because the load is shared by two different cross-sectional areas of the bolt), or 22,634 psi.

	Stress Concentration
		These flaws cause the stress surrounding the flaw to be amplified where the magnification is dependent upon the orientation and geometry of the flaw.
		Stress raisers are defined as the flaws having the ability to amplify an applied stress in the locale.
		The stress concentration factor is a simple measure of the degree to which an external stress is amplified at the tip of a small crack.

	Method for making an article portion subject to tensile stress and stress relieved article - Patent 6210108
		During cyclic operation of the engine, such tensile stress results from a cyclic type of bending of the band, sometimes referred to as chording.
		The relatively high amount of tensile stress can be sufficiently high to result, during operation, in the formation of a LCF crack in the band.
		The LCF crack in the band extends from the high tensile stress portion of the band generally toward, and stops at, the band portion under compressive stress or lower tensile stress.

	Norris Products - Failure Analysis - Failure Mechanisms
		Stress raisers are visible or microscopic discontinuities that cause an increase in local stress on the rod string during load.
		A tensile failure is characterized by a reduction in the diameter of the cross-sectional area at the point of fracture.
		The tensile failure is secondary and results in the unusual appearance of the fracture surface-with the small fatigue portion, large tensile portion and unusually large 45A double shear tears.

	Unified Threadforms Help
		The tensile stress area is the area of a cross-section of the bolt according to the familiar formula of pi multiplied by the square of half the diameter.
		In the usual calculation of the tensile stress area, the number used for the diameter is the mean of the maximum pitch and root diameters of the bolt.
		Changing the formula for tensile stress area also affects the calculation of preload which produces a dubious effect on the calculation of the torque required to induce the preload and reduces the estimate of thread shear stress for both nut and bolt threads.

	Assessment of tensile residual stress mitigation in Alloy 22 welds due to laser peening
		Residual stress profiles were measured in Alloy 22 base material using the slitting method (also known as the crack-compliance method), and a full 2D map of longitudinal residual stress was measured in the sample welds using the contour method.
		The depth of compressive residual stress was found to have a, significant dependence on the number of peening layers and a slight dependence on the level of irradiance.
		Additionally, laser peening produced compressive residual stresses to a depth of 4.3 mm in the 33 mm thick weld at the center of the weld bead where high levels of tensile stress were initially present.

		In fluids that are in motion the components of the shear stress are not zero and generally the stress in the fluid is also not isotropic, so it is not possible to speak of "the" normal stress in a point.
		The shear stress belongs, in its entirety, to the deviator stress.
		Variations in the isotropic part of the stress (tension or pressure) result in changes in the volume of the gas or fluid, while variations in the deviator stress result in changes in the shape of the gas or fluid (usually resulting in the fluid or gas being in motion).

	ServoCon ALPHA: Glossary
		In tensile tests of thin sheet materials or materials in form of small diameter wire it is difficult to distinguish between breaking load and the maximum load developed, so the latter is considered the breaking load.
		It is the stress at the point of tangency between the stress- Elastic Hysteresis strain curve and the line having a slope, with respect to the stress axis, 50% greater than the slope of the curve at the origin.
		Stress concentration factor usually is higher than the empirical fatigue notch factor or strength reduction ratio, because it does not take into account stress relief due to local plastic deformation.

	Omega Atomizers \| Stress Corrosion Cracking In SDA Systems
		Tensile stress is the kind of force that pulls things apart, like stretching a rubber band.
		Tensile stress is also a component of bending stress or shear stress or compressive stress.
		Since tensile stress is required for stress corrosion cracking and the corrodant is present on the surface of the material only, compressive stress on the surface of the part can be beneficial.

	STRESS INVOLVED CORROSION MECHANISMS
		The tensile stress ruptures films at the crack tip and the crack grows rapidly from the bare metal exposed until the crack tip can repassivate in some cases or grow slowly to failure in other cases.
		The loss of the film stress and plasticity in the metal than blunts the crack and stops it growing to give periods of crack growth followed by rest while the film grows back to the conditions for cleavage.
		The stress to initiate a crack then decreases and a crack grows until it is blunted by plastic deformation or grows out of the adsorbed region.

	Tensile-Strength Tests
		The ultimate strength is represented b y the maximum ordinate to the stress-strain curve at C. The stress-strain diagram for steel in compression is essentially similar to the curve as described for tension, and the elastic limit is approximately the same in both cases.
		In this test the ultimate tensile strength, the yield point, the percent elongation, and the character of the fracture are determined.
		If the stress at all loads was computed upon the basis of the actual section then existing, instead of being computed (as it usually is) upon the basis of the original section, the stress-strain curve would follow such a course as is indicated by the dotted-line curve 3 of Figure 1.

	Stress and Strain
		Stress is a measurement of the strength of a material, strain is a measure of the change in the shape of the object that is undergoing stress and elastic modulus is a measurement of the amount of stress needed to change the shape of the object.
		For tensile stress, the elastic modulus is called the Young's modulus and is denoted by Y.
		When a material is stressed, the dimensions perpendicular to the direction of the stress become smaller by an amount proportional to the fractional change in length.

	Mechanical Properties of Polymers
		Tensile strength is important for a material that is going to be stretched or under tension.
		Since tensile stress is the force placed on the sample divided by the cross-sectional area of the sample, tensile stress, and tensile strength as well, are both measured in units of force divided by units of area, usually N/cm
		Modulus is measured by calculating stress and dividing by elongation, and would be measured in units of stress divided by units of elongation.

	Tensile Fracturing of Stiff Rock Layers under Triaxial Compressive Stress State
		As the host conglomerates could not transmit tensile stresses, these authors proposed that the tensile fracturing occurred due to the stress amplification associated with the stiffness contrast between the pebbles and the conglomerate.
		The stress amplification within a stiff inclusion is defined here by the ratio between a stress component in the inclusion and the corresponding stress component in the medium.
		As the stiffness ratio depends on the lithology of the limestone layers, the amplified stresses would prevail as long as the tectonic stresses are active, leading to continuation of the fracturing and to the observed high fracture density.

		This corresponds to the load reaching a maximum, at which point the tensile deformation is inhomogeneous and strain is no longer uniform.
		The average stress based on original area likewise decreases, and this produces the fall-off in the stress-strain curve beyond the point of maximum load.
		If the true stress, based on the actual cross-sectional area of the specimen, is used, it is found that the stress-strain curve increases continuously up to fracture, as shown in Fig 2.
