 BME 332: Mathematical Preliminaries
Although understanding index notation, vectors and tensors may seem esoteric at first, it is really the foundation, or language, needed to first understand continuum mechanics and then to apply continuum mechanics to the study of biosolid mechanics.
Tensors may be thought of mathematically as linear operators that act on either a vector or tensor to generate another vector or tensor.
For example, the eigenvalues of stress and strain tensors are the prinicpal stress and strain, while the eigenvectors are the direction of that stress and strain.

In mathematics, a tensor is a certain kind of geometrical entity and array concept.
It generalizes the concepts of scalar, vector (spatial) and linear operator, in a way that is independent of any chosen frame of reference.
Tensors are of importance in pure and applied mathematics, physics and engineering.

A pure tensor of V \otimes W is one that is of the form v \otimes w.
In the tensor algebra T(V) of a vector space V, the operation \otimes becomes a normal (internal) binary operation.
These are the derived functors of the tensor product, and feature strongly in homological algebra.

 Reference.com/Encyclopedia/Tensor contraction
In mathematics, the contraction of a tensor in multilinear algebra occurs when a pair of literal indices (one a subscript, the other a superscript) of a mixed tensor are set equal to each other and summed over.
The result is another tensor with rank reduced by 2.
If a tensor is dyadic then its contraction is a scalar, which is obtained by dotting each pair of base vectors in each dyad.

There has been some argument as to which version of the 2D wavelet bases should be used for various applications [5] 13] Our strategy toward this problem is this: we can put as many versions of these bases in the library as we can afford it in terms of computational time.
Of course, in the case A = 2I and J = 1 with which we deal, the single dyadic orthonormal wavelets that we construct are not associated with MRAs, because of the aforementioned MRA....

As demonstrated in Eq.(9.1.27a) and Eq.(9.1.27a), the bracketed term in Eq.(9.1.21) has all of the properties of the moment of inertia tensor whose components are given in Eq.

 Elasticity by Pei Chi Chou and Nicholas J. Pagano and Chou : Booksamillion.com (0486669580, Paperback)
It is especially useful because it offers the theory of linear elasticity from three standpoints: engineering, Cartesian tensor, and vector-dyadic.
The latter part of the text, after Cartesian tensor and dyadic notations are introduced, gives a more general treatment of elasticity.
Most of the equations of the earlier chapters are repeated in Cartesian tensor notation and again in vector-dyadic notation.

 Semi-analytical elastic wave-field modeling applied to arbitrarily oriented orthotropic media   (Site not responding. Last check: 2007-10-29)
Three-dimensional elastic wavefield calculation is addressed for the case of orthotropic materials with arbitrary spatial orientation.
Based on a mathematical formulation involving Green's dyadic displacement tensor function, appropriate evaluation yields a representation of the displacement vector of transducer wavefields in anisotropic media which is convenient for effective numerical computation.
With respect to bulk wave propagation the numerical evaluation of Green's dyadic function is circumvented by applying a reciprocity-based approach, which is valid in the (point source) far-field.
