WebUniversity of Washington WebFor our model, this gives a critical load of 62.5 N/mm. The eigenvalue buckling analysis with 20 linear open section beam elements predicts a critical load of 62.47 N/mm. The load-displacement analysis shows a severe loss of stiffness at a load very close to the expected critical value, as shown in Figure 4.

WebBending can induce both a normal stress and a transverse shear stress. The existence of this shear stress can be seen as cards slide past each other slightly when you bend a deck of cards. The magnitude of the shear stress becomes important when designing beams in bending that are thick or short – beams can and will fail in shear while bending.
