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 ...

Force‐Induced Control of Circularly Polarized Luminescence With Rotaxane Architecture
Angewandte Chemie, EarlyView.Force‐induced reversible on/off switching of circularly polarized luminescence is achieved with a rotaxane‐based supramolecular mechanophore. The mechanophore, featuring a chiral helicene luminophore, is incorporated as a first network cross‐linker into a double‐network organogel.
