OOF2: The Manual

Details

Description

An anisotropic stress-free strain Property makes an additive contribution of

to the Stress, where $C_{ijkl}$ is the Material's elastic modulus, and ${ϵ}^0$ is a symmetric second rank tensor given by the epsilon0 parameter.

If the only contributions to the Stress are linear elasticity and stress-free strain, then the full Stress is

so ${ϵ}^0$ is the strain at which the Stress vanishes.

The crystal symmetry of the material is reflected by the symmetry of the strain, epsilon0. The symmetry of the stress-free strain should probably be compatible with the symmetric of the elasticity, although OOF2 does not enforce this restriction. Materials containing an anisotropic stress-free strain Property must also contain an orientation property.
