Progressive Strain

A special plate-shaped specimen with two symmetrical, straight air gaps in the center portion and a pair of holes for load chucks at the end portion is used for thermal-stress ratcheting experiments. Experimental results on strain growth due to thermal-stress ratcheting are presented for specimens made of types 304 and 316 austenitic stainless steel. The results cover cumulative and incremental strain growths under conditions of load variation and the effect of hot to cold bar area ratio.

This paper studies the cyclic ratcheting for two materials under multiaxial stress state. The two materials are SUS304 austenitic stainless steel and A1070 pure aluminum. The former material is known as a material that gives strong additional hardening and the latter material shows little additional hardening under nonproportional cyclic loading. The ratcheting behavior under 12 stress-strain waveforms was extensively studied using hollow cylinder specimen. Ratcheting strain depended on the material and stress-strain waveform. Anisotropic ratcheting was found in A1070 but isotropic ratcheting was observed in SUS304 steel.
