Example Definition
The definition below is given by the Result Math expression built using an OptiStruct model (*.fem) and the relevant results (*.op2) where Composite Stress had been requested through the CSTRESS(OUTPUT2) control card and material allowables had been assigned to the MAT8 card for Xt,Xc,Yt,Yc and S values.
The Hashin Failure criteria for Matrix output has been selected.
