Plastic intermittency during cyclic loading: From dislocation patterning to microcrack initiation [PDF]
Physical Review Materials, 2019 In metallic materials subjected to cyclic loading, strain hardening as well as fatigue crack initiation have been linked for a long time with the evolution of dislocation patterns and structures. In particular, the development of low-energy dislocation configurations such as persistent slip bands (PSBs) is considered as a precursor to crack initiation.

Intermittent cyclic loading of cartilage explants modulates fibronectin metabolism
Osteoarthritis and Cartilage, 1997 The aim of this study was to evaluate systematically the effect of tissue load, its amplitude, time of intermittence and duration of loading on the biosynthesis and release of fibronectin by intermittently loaded mature bovine articular cartilage explants.Cyclic compressive pressure was introduced using a sinusoidal waveform of 0.5 Hz-frequency with a ...
