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…
