convergence problem in interface delamination modeling in ansys
hi every body..
im trying to model interface delamination in ansys. i use inter204 or 205 for interface element.the problem is that as the stress in interface riches the yield value, the solution doesnt converge.
i tried to increase the number of substeps or decrease the size of element, but the problem still exists.
input stiffness matrix to ansys
Hi everybody
Im working on a project about Finite element modeling of Contact. Im not allowed to use contact solving feature of ANSYS and i should use its Macro Programming. in this case i should read stiffness matrix from ansys, add some row and column to it and input it back to ansys and solve it.
I have two problem with this, first i dont know how to input modiffied stiffness matrix back to ANSYS..
swiching Nodal Result output to Integration Points in ANSYS
Hi every body
i modeled a plane with a notch with elastic-perfect plastic material. somewhere in model the stress reaches above the yield stress
so i think the reason is that ANSYS reports the nodal result output by default wish they interpolated from integration points results.
i want to see the integration points results but i dont know where to finde them.
