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.
WebIn a cylindrical vessel, the length represents the length over which the shell behaves as a ring. A further restriction on secondary stresses is that they may not be closer to another …
