Strain results

[yusf]

Hi all, i am currently working on composite analysis with Patran/Nastran combination...after running model i obtain some strain values such as Component and Eng Component ..My question is that which one of those values is used for design allowables?...i mean which one i must take care on..As i know from theory Componnet value is two times of Eng component.. it means that if i make selection mistake i will be two times in failure region..i will be waiting your comments

thanks in advance
