Options::String Elasticity::ConstitutiveRelations::AnisotropicHomogeneous::StiffnessMatrix::help
staticconstexpr
Initial value:
= {
"Symmetric, positive definite 6x6 stiffness matrix in Voigt "
"notation (smallest eigenvalue > 1e-12 (`min_relative_eigenvalue`) "
"times the largest). Interpreted with engineering shear strains: "
"[Sxx,Syy,Szz,2Syz,2Sxz,2Sxy]. Entries are in the same units of "
"stress as the other materials (e.g. GPa in the input files)."}
