...Abstract Abstract This chapter provides a detailed analysis of the cyclic stress-strain behavior of materials under uniaxial stress and strain cycling. It first considers the case of a stable material under constant-amplitude strain cycling then broadens the discussion to materials that harden...

For a relatively thin component (or test specimen), there essentially is no lateral constraint (in the direction of the thickness), and plane-stress conditions dominate. Using either of these constraints in stress-field analysis allows two-dimensional solutions of three...
