The Recovery Props Library

The recovery props library provides a set of function to check and evaluate the properties of stiffness and compliance tensors.

void check_symetries(mat L, string umat_type, int axis, vec props, int maj_sym)

Check the symmetries of a stiffness matrix L, and fill the vector of material properties. Depending on the symmetry found, the string umat_type, the axis of symmetry (if applicable) the vector of material properties, and the major symmetry maj_sym (L_ij = L_ji ?). If the major symmetry condition is not fulfilled, the check of symmetries if performed on the symmetric part of L

Material Symmetries considered

Fully anisotropic	ELANI	0	0
Monoclinic	ELMON	1,2 or 3	0
Orthotropic	ELORT	0	9
Cubic	ELCUB	0	3
Transversely isotropic	ELITR	1,2 or 3	5
Isotropic	ELISO	0	2
