How to simulate failure theory of laminate

Hi,

The script specified is a a subroutine written by the company. 

Usually you can include failure theory within PCOMPP/PCOMP and look at the failure indices or Strength ratios to know about integrity of the ply.

ok thanks and where can i find the failure indices?

@hubéry10

Please add CFAILURE to output failure indices.

Go to Control Cards>> Global Output Request>> CFAILURE. Also make sure you have selected SOUT>>YES in PCOMP/PCOMPG to write out failure indices, composite stress, strain for individual plies.

Please note:  When CFAILURE is not present, composite strength ratios are not output. CSTRESS and CSTRAIN entries cannot be used to request failure indices.

I selected SOUT in PCOMP and have Input ST, SC, SS(MAT1) ; Xt, Xc, Yt, Yc, S(Mat8) but CFailure is not presented. So whats my mistake?

Hi,

What is the version of HyperWorks are you using?

as a workaround, please edit the model file in any text editor and add the CFAILURE card as shown below:
