General composite pre-proc. for OptiStruct

Hi,

i have some difficulties regarding composite pre-processing. For my composite analysis (a basic rectangle plate with tension and bending load) I made following requests:

CFAILURE (h3d,NDIV=1) = ALL in CASE_UNSUPPORTED_CARDS (for max strn failure criteria or let's say a specified failure criteria)
CSTRAIN and CSTRESS (FORMAT: H3D)
SRCOMPS (VALUE: YES) for the strength ratio

In HyperView, I can't see my SR-results. The results i get by the listed requests are:

Composite Failure (should be design load/allowable load; am I right?)
Composite Strains
Composite Stresses
Composite Strength => Is this the strength ratio?

Best regards

Hi Musti,

Yes, composite Strength is written to H3D because of composite strength ratio output in PARAM.

Hi Prakash,

thank you for your quick reply. The strength ratio (SRCOMPS) is defined as 1/(Failure index) for max. strn criteria. I've just checked the composite strength (strength ratio) by dividing 1 by the failure index as described in SRCOPMS and the value was correct. I was a bit confused due to the new denotation.
