6.3 Anisotropic Elasticity - Auckland
6.3.2 Orthotropic Linear Elasticity An orthotropic material is one which has three orthogonal planes of microstructural symmetry. An example is shown in Fig. 6.3.2a, which shows a glass-fibre composite material. The material consists of thousands of very slender, long, glass fibres bound together in bundles with oval cross-sections.

10 Viscoelasticity 00 - Auckland
pkel015.connect.amazon.auckland.ac.nzLinear Viscoelasticity Linear viscoelastic materials are those for which there is a linear relationship between stress and strain (at any given time), . As mentioned before, this requires also that the strains are small, so that the engineering strain measure can be used (since the exact strain is inherently non-linear).
2 The (Galerkin) Finite Element Method - Auckland
pkel015.connect.amazon.auckland.ac.nzElement Method (GFEM), the domain is subdivided into finite elements. The function is approximated by piecewise trial functions over each of these elements. This is illustrated below for the one-dimensional case, with linear functions used over each element, p being the dependent variable. Figure 2.1: A mesh of N one dimensional Finite Elements ...

The main difference is that the cylinder has three different principal stress values, the circumferential stress, the …
Stress Balance Principles 03 The Cauchy Stress Tensor
pkel015.connect.amazon.auckland.ac.nz•the Cauchy stress refers to the current configuration, that is, it is a measure of force per unit area acting on a surface in the current configuration. Stress Components Taking Cauchy’s law to be true (it is proved below), the components of the stress tensor with respect to a Cartesian coordinate system are, from 1.9.4 and 3.3.4, (j) ij i j i
10.2 Examples and Applications of Viscoelastic Materials
pkel015.connect.amazon.auckland.ac.nz10.2 Examples and Applications of Viscoelastic Materials Some of the properties of viscoelastic materials are their ability to creep, recover, undergo stress relaxation and absorb energy. Some examples of these phenomena are discussed in this section1. 10.2.1 Creep and Recovery The disks in the human spine are viscoelastic.
