ubackwardeuler()

subroutine, public muyield::ubackwardeuler	(	real(kind=kreal), dimension(:), intent(in)	matl,
		real(kind=kreal), dimension(6), intent(inout)	stress,
		real(kind=kreal), intent(in)	plstrain,
		integer(kind=kint), intent(inout)	istat,
		real(kind=kreal), dimension(:), intent(inout)	fstat,
		real(kind=kreal), intent(in)	temp,
