Detailed Description

This class defines material model for simple creep modelling which uses effective Young modulus approach. The model is reasonable only with elasttime material model.

Order of internal variables in the other array : ----------------------------------------------- 0-ncompstr : computed "irreversible creep strains"

Member Function Documentation

double give_actual_ft	(	long	ipp,
		long	im,
		long	ido
	)

This function returns the value of tensile strength

Parameters:

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

void giveirrstrains	(	long	ipp,
		long	im,
		long	ido,
		vector &	epscr
	)

This function updates values in the other array reached in the previous equlibrium state to values reached in the new actual equilibrium state.

Parameters:

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

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

Function computes material stiffnes matrix.

Parameters:

	d	- allocated matrix structure for material stiffness matrix
	ipp	- integration point number
	im	- material index
	ido	- index of internal variables for given material in the ipp eqother array

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

Function computes correct stresses in the integration point and stores them into ip stress array. This material is reasonable only in combination with ELASTTIME material, which deals with effective Young modulus.

Parameters:

	ipp	- integration point pointer
	im	- index of the material in the ipp tm and idm arrays. The standard value is zero.
	ido	- index of internal variables for given material in the ipp other array

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

This function updates values in the other array reached in the previous equlibrium state to values reached in the new actual equilibrium state.

Parameters:

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