4.2. It is an element which is isotropic in its elastic coefficients, but is orthorhombic in its thermal expansion coefficients. It can be used to simulate transformation strains or residual stresses where the elastic coefficients are not known precisely, but the expansions are known not to be isotropic.
- elastic coefficients
- The elastic coefficients young and poisson have the same
meaning as they do in the isotropic element (Section
- thermal expansion coefficients
- The thermal expansion coefficients a1, a2, and a3 are the
diagonal components of the thermal expansion tensor .
4.3 [inverse temperature]
- Without rotation, the thermal expansion coefficient a1 governs
expansion in the direction, a2 in the direction, and
a3 in the direction (out of the screen). See Section
