What is Ratcheting?
A progressive accumulation of plastic strain, called strain ratcheting, occurs in ductile materials, subject to asymmetrical inelastic cyclic stressing. Ratcheting is characterised by a shift in the stress-strain hysteresis loop along the strain axis and incremental inelastic deformations. The ratcheting phenomenon is of paramount importance in the design procedure of systems, which undergo inelastic cyclic…
Application of Digital image correlation in cycling loading
DIC is an optical method that employs tracking and image registration techniques for accurate 2D and 3D measurements of changes in images. This method is often used to measure full-field displacement and strains, and it is widely applied in many areas of science and engineering. [1] This new testing procedure can help to obtain more…
