ABSTRACT (Continue en reveree aide If neceeessy and Identify by block number) Within the framework of an existing purely mechanical, rate-type theory of L&J plasticity detailed calculations are presented for certain types of material §response during stress and strain cycling in a uniaxial homogeneous deforma-LL. tion. These features pertain specifically to material response in stress cycling between fixed values of stress in tension and compression (not necessarily equal in magnitude) resulting in ratcheting of strain, and
