Detailed Description

The class defines elastic orthotropic material given by the stiffness matrix de in the local coordinate system of the material. There must be also defined transformation matrix t whose components represent general functions (gfunct). The components of the matrix t must be evaluated with respect to space coordinates of the given integration point.

Member Function Documentation

void give_transf_mat	(	matrix &	tmat,
		long	ipp
	)

returns transformation matrix from the local material coordinate system to the global one

The function returns transformation matrix from the local material coordinate system to the global one in the argument. Components of the transformation matrix are evaluated with respect to space coordinates of the given integration point ipp. The argument tmat is supposed to be allocated to dimensions 3x3.

Parameters:

	tmat	- evaluated transformation matrix
	ipp	- integration point id

Returns:

The function returns transformation matrix in the argument tmat
