Ansys Failure Criteria

Submitted by cube on Thu, 2008-05-22 06:29.

Hello, I am trying to run a laminted composite plate in ansys. I have all the required mechanical properties and the know how to put some of the information. So far, the many trials I did i can't extract the failure criteria results. I want to know whether the plate fails in normal, shear or compression. I appreciate if someone can give me the map of how to get to that result and at what force. what are the step that i have to take in order to get there.

thanks

Mat

APDL can solve your problem by performing an simple code

Here, I have dealt with your problem successfully. I implement the code using APDL in ANSYS, which is employed as interface to the main program.

So, I suggest you conduct an subroutine using APDL in ANSYS to link the failure criteria to the main program.

I think the function of ANSYS is not strong for simulating the failure and damage of the laminated structures, especially the plastic post-buckling collapse because I have been concentrating on this reseach recently.
