How to set up a composite analysis

Rahul_P1

Hello,

to set up a composite analysis for OptiStruct, you might follow the following the steps within these tutorials:

http://training.altairuniversity.com/analysis/structural/composites/analysis-of-a-composite-plate-video/

http://training.altairuniversity.com/analysis/structural/composites/modeling-and-analysis-of-composite-structure/

There are more Tutorials available in the HyperWorks Help -> Tutorials -> Solver Tutorials -> OptiStruct

Please note that in order to write stress and failure data (e.G. Tsai-Wu) from an OptiStruct Composite Analysis, you need to activate the following solver input:
- The material (MAT 8 for shells) needs a statemend on the allowable Yield Limits for stress or strain
- The Property (Pcomp) or the Plies (in case of ply based modelling approach) need a statement for stress output --> SOUT = YES
- The Composite Stress and Strain output finally needs to be activated in the subcase options or globally for all subcases by using setup --> create --> control cards --> global output options --> CSTRESS and CSTRAIN

Please let us know, if you need further advice

Hi,

 

I used to be able to set up a composite analysis in HyperMesh 12, but in HyperMesh 13 I can't retrieve the failure index results.

I followed everything in the 'OS-4050: Optimization of a Horizontal Tail Plane' tutorial, but no matter whether I use HILL or TSAI (actually I would like to use TSAI) failure criteria, after the run is completed, in there is no 'Ply Failure' result in HyperView.

 

I attached the file. Please rename the extension from *.txt to *.hm.

 

Thank you
