Short beam shear stress.. Is it the right one for PCOMP card?
Short beam shear stress.. Is it the right one for PCOMP card?
(OP)
I am doing simple buckling analysis on a carbon fiber tublar product subject to compressive load. I use NE nastran. My model contain PCOMP card and MAT8 card. I have the material property for the carbon prepreg from the supplier from which I am pluging in all the values in MAT8 card. In MAT8 card, there is a coloumn for shear strenth value in XY plane of fiber. The material data what I have contain short beam shear stress in 0 degree and 90 degree as per ASTM std. Which one is the right value to be pluged in for this shear stress value? I am interested in seeing failure critria of all the plies in the laminate.
Thanks
Thanks

Regarding failure criteria, Am I required to use strain values for corresponding stress values (xt,yt,xc,yc,S) in MAT8 card? If I plugin allowable/failure strain values for material properties, Can I still use other failure theories like Tsai or Hill or Hoff or LARC02? Or I can only use max strain theory?
