Strain Hardening of 316FR Steel in Strain-Controlled Ratchetting Deformation.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1997 This paper is concerned with the strain hardening of 316FR steel subjected to strain-controlled ratchetting deformation, i.e., cyclic straining with maximal strain increasing at every cycle. First. by discussing isothermal and nonisothermal experiments in this type of deformation, it is shown that the isothermal stress versus strain hysteresis loops ...

Ratchet analysis of structures under a generalised cyclic load history
, 2014 This paper introduces a new approach based upon the Linear Matching Method in order to obtain the ratchet limit of structures subjected to an arbitrary thermo-mechanical load history. This method varies from the traditional Linear Matching Method ratchet
