Ansys composite modelling and analysis

Submitted by Hallgeirda on

Hi Have for a period been searching for tutorials of how to build a composite (and doing an analysis, eigenvalue, Euler-buckling, first ply) model in Ansys.Have been able to find a couple of examples in the Ansys-portal examples search, have after reviewing the different options decided that shell91 will be a appropriate element type for me. (because of nonlinear capabilities)Referring to "152191 - Example of new Failure criteria (FC) method for shell91 vs. old method", shows the basics of how to build a composite specimen of 5 layers, and using new and old FC (Tsai-Wu). I have been trying to expand this example to 10 layers, but I am encountering some problems during solution. The Ansys documentation is not very good, and does not give much help.I am familiar with Ansys, but not with composites analysis in Ansys.Can anyone give me any hints/tips on this?Much appreciated..!!SKR

Anyway work with shell 181 it's much easier. Just an example how to define sections

v\:* {behavior:url(#default#VML);}
o\:* {behavior:url(#default#VML);}
p\:* {behavior:url(#default#VML);}
.shape {behavior:url(#default#VML);}
v\:textbox {display:none;}
