Hello everyone.
I'm trying to apply the Tsai-Wu criteria to a composite plate in ANSYS. I'm using the SHELL99 element.
However, when I input the data for the criteria an error occours and ANSYS won't show me any results on the criteria.
Can someone help me? How do I use this criteria and what data should I use?
Thanks in advance
I see that people talk a lot about ANSYS over here and that is the software that I use during my works at university. However, when I read some papers or attend some conferences I hear about other finite element programs such as ABACUS and NASTRAN. Besides that I've also seen other open-source codes such as SALOME, Code-Aster, etc...
What do you think is the best software to make finite element analisys, or if it's difficult to say wich one is best, what are the weak and strong points of each software?
