The H-beam is made of an elastic-plastic material for which σy =
400 MPa. Find the plastic moment Mp and the maximum elastic moment
Me and determine the shape factor for the cross section of the
H-beam. Also, determine the residual stresses in the top and bottom
of the beam after the plastic moment MP is applied and then
released.
