Plane stress

  1. Sep 7, 2016 #1
    1. The problem statement, all variables and given/known data
    my notes gave that in a 3d cubic , plane stress is state of stress in which two surfaces are free of stress ....

    2. Relevant equations


    3. The attempt at a solution
    Does it mean the we only consider the stresses in xy plane only ? because the object is too thin, so we assume it's 2 dimensional only ?

    if so , the statement in the notes should be rewrite as 4 surfaces of cubic element is free of stress , right ? Since we only consider the stresses in 2 planes out of 6 planes , right ?
