void matstiff	(	matrix &	d,
		long	ipp,
		long	ido
	)

This function computes material stiffness matrix considering layer stiffnesses.

	)

void nlstresses	(	long	ipp,
		long	im,
		long	ido
	)

This function computes stresses at given integration point ipp, depending on the reached strains. The stress and the other attribute of given integration point is actualized.

Parameters:

	ipp	- integration point number in the mechmat ip array.
	im	- index of material type for given ip
	ido	- index of internal variables for given material in the ipp other array
