Numerical simulation of ratcheting and fatigue behaviour of mitred pipe bends under in-plane bending and internal pressure [PDF]
, 2013 This paper investigates the ratcheting and fatigue behaviour of 90 degree single unreinforced mitred pipe bends subjected to a cyclic in-plane closing moment with a non-zero mean value and constant internal pressure. An experiment was conducted to induce

Bi-axial Strain Accumulations in Mechanical Ratcheting
Bulletin of JSME, 1984 Bi-axial strain accumulations in both axial and circumferential directions are observed in the mechanical ratcheting tests conducted by subjecting thin-walled tubular specimens to combined steady internal pressure and cyclic axial loading. The direction and magnitude of ratcheting strain are examined, as functions of maximum stress, stress ratio ...

Characterization of the material response in the granular ratcheting [PDF]
, 2005 The existence of a very special ratcheting regime has recently been reported in a granular packing subjected to cyclic loading \cite{alonso04}. In this state, the system accumulates a small permanent deformation after each cycle.
