my "stiffness" matrix comes out singular?

Hi there,

I am running into a problem where for a simple, 2D, axisymmetric, single element problem, I get a "singular" matrix for my stress.  Consequently my force equilibrium equations cannot be solved for the displacements at the nodes.

The principle stresses for the axisymmetric case are as usual, a 4x1 matrix sigma given as:

[sig1, sig2, tao, sig3]^T and obtained as:

[sigma]=[D][S][B3][u]

(my problem is that [D][S][B3] a 4x8 matrix for a four node axisymmetric element always comes out singular for the first load increment)

zero pivot problem in 3d vcct delamination modeling

Dear all,

I'm trying to modeling an 3d Mode I delamination problem using VCCT method. C3DR8 element is used thereby. Every time after submitting the job it warned me with that "Solver problem: zero pivot...". I assume it may be caused by over-constraint, but I can't find where  I exactly goes wrong. I've uploaded the .inp file. Could anyone can give me a hand? Thanks a lot.

determination of stiffness matrix of transversely isotropic material

Dear all, I am an applied mathematician and I  have been stucked by the this general question for a while, i.e.,  to determine the stiffness matrix of transversely isotropic material from known strain and stress tensors.  The definition of transversely isotropic tells us that the stiffness matrix can be defined by 5 constants, see attached figure. C44 is easy to determine, so we can focus on the remaining 4 constants. I attempted to establish 4 linear equations for these 4 constants with the known strain and stress components.
