Stress-Strain Analysis of Cyclic Plastic Bending and Torsion

Analysis of stresses, strains, and damping energies is considered for cyclic loading of simple geometries. For beams under pure bending and for circular shafts under torsion, it is shown that cyclic loading may be handled by analysis that differs from that applicable to monotonic loading only by the substitution of a cyclic stress-strain curve. Analysis and experiment are successfully compared for rectangular beams of an alloy steel.
