    FEA for double shear

    Shiyan Jayanath

      Hi all,


      I'm doing a FEA analysis for pin which subjected two double shear. I calculated the maximum shear stress of the pin using FEA and as well as manual calculation.

      This equation used for theoritical calculation

      Max shear stress =(Force/2)/ area of minimum cross section.


      But When i'm comparing two results, FEA result is always approximately two times larger than the theoritcal value.

      Can any one figure out why this happens?


      I've attached screen shots for ur reference.

      I used advanced fixture- symetric for this analysis and fixed geometry appllied only for portion of the cylindrical body. see the attachement 1.
