Influence of Residual Stress on the Initiation of Fatigue Cracks at Welded Piping Joints
… Carolina State University (NCSU) pointed to the strain ratcheting response of the welded joint as a probable reason for fatigue failure and indicated that welding residual stresses might be responsible for inducing this strain ratcheting response. It was the primary objective in this …

Integral bridge abutment and backfill behaviour
… bridge deck leads to the accumulation of soil strain — known as strain ratcheting — which results in increased lateral earth pressures along with settlement at the bridge approach. Uncertainty surrounding strain ratcheting is reflected through design restrictions. This research investigated …

Numerical Modeling Issues in Finite Element Simulation of Plasticity Induced Crack Closure With an Emphasis on Material Model Effects
… and Frederick's model) and nonlinear plastic strain evolution (Lubliner's generalized plasticity)---into a 3D small scale yielding boundary layer approximation of a mode I crack. With the traditional method of growing the crack by one element per load cycle, the results display strong …
