Short Edge Margin

  1. Aug 9, 2008 #1
    Hello All,
    I have short edge margin condition of 1.36D on one of the part.Actually 3 parts of aluminum are joined together by bolts and one part has short edge margin.

    All the parts have sufficient bearing strength.So if I understand right bearing failure occurs before shear-tear-out-failure.So if this is right then is 1.36D okay to prevent shear-out as there is no bearing failure due to sufficient bearing strength?

    Thanks

    Hi
    If somebody is confused I just want to say that my bearing allowable is much higher than shear tear out so I think I shouldnt be worried for shear-tear out failure even though it is 1.3 D<2D.

    Am I right in this?

    And is shear tear out always occur after bearing failure?

    Thanks
