function y = OrthotropicCompliance(E1,E2,E3,NU12,NU23,NU13,G12,G23,G13)
%OrthotropicCompliance This function returns the compliance matrix
% for orthotropic materials. There are nine
% arguments representing the nine independent
% material constants. The size of the compliance
% matrix is 6 x 6.
y = [1/E1 -NU12/E1 -NU13/E1 0 0 0 ; -NU12/E1 1/E2 -NU23/E2 0 0 0 ;
