Calculation of the elastic constants If an external force acting on a body or if one part of the body applies force on
 

Summary: Appendix A
Calculation of the elastic constants
If an external force acting on a body or if one part of the body applies force on
another part, it is said that the body is in a state of stress. Stress is defined in units
of force per unit area = F/A and can be characterized in the general case by the
stress tensor. Strain describes the state of deformation of a solid; there is dilatational
strain which changes the volume, but not the shape and deviatoric strain which in
contrast changes the shape, but not the volume.
For a field of deformations u = (x y z), we can define a symmetric strain tensor
in the following way:
=
