Function Documentation

function Ke = ElemStiffElasMatP1BaOptV0	(		ql,
			area,
			C
	)

Computation of the element stiffness elasticity matrix for -Lagrange method. The method for numbering the degrees of freedom is local alternate numbering (classical method)

Hooke's matrix

C=[L + 2*M L 0] [ L L + 2*M 0] [ 0 0 M]

Numbering of local points in reference element is

P=[(0, 0), (1, 0), (0, 1)]

Example:

        ql=[0 1 0;0 0 1];
        area=1/2.;
        lambda=1.; mu=1.;
        C=[lambda+2*mu, lambda, 0;lambda, lambda + 2*mu, 0;0, 0, mu];
        Elem=ElemStiffElasMatP1BaOptV0(ql,area,C);
