Can elasto-plastic stiffness matrix be unsymmetric?
Can elasto-plastic stiffness matrix be unsymmetric?
(OP)
I think elasto-plastic stiffness matrix will be unsymmetric when yielding function and plastic potential function are not the same one. Am I right?
If it is true, how to solve the equations in nonlinear finite element anasysis?
