    Hi @tiago3008

     

    The issue is with the MAT1 card which doesn't support any of orthotropic failure theories.

    Hi @tiago3008

     

    In order to get strength ratio when an iso material is used, make sure you provide ST, SC and SS (strength limits in tension, compression and shear) on MAT1 card. 

     

    These parameters are used for composite ply failure calculations. Please refer to help for more information.

    I have requested PARAM-SRCOMPS-YES, also CSTRESS from Global output request and SOUT-YES for all plies. I could see Composite Failure and Failure Index in Hyperview, but not  the strength ratio. why ? I appreciate any help on this.
