A material with orthorhombic symmetry has 9 independent elastic constants and 3 independent coefficients of thermal expansion. See figure 4.3.


The orientation of the crystalline axes. See Section 4.3. [degrees]

elastic coefficients
The components of the stiffness matrix are specified by the values of c11, c12, c13, c22, c33, c44, c55, and c66. [stress]

thermal expansion coefficients
The three independent coefficients of thermal expansion are specified by alpha11, alpha22, and alpha33. [inverse temperature]
