Effect of Compressive Residual Stress on the Corner Crack Growth

In the present study, plasticity induced crack closure (PICC) concept and three dimensional (3D) finite element methods (FEM) are used to study the effect of compressive residual stress field on the fatigue crack growth from a hole. To investigate the effect of compressive residual stress on crack opening levels and crack shape evolution, Carlson’s experiments were simulated. Crack shape evolut...

A Simplified Residual Stress Model for Predicting Fatigue Crack Growth Behavior 'at Coldworked Fastener Holes

This paper presents an investigation of the fatigue crack growth (FCG) behavior at fastener holes in a high strength steel. 30CrMnSiNi2A, before and after a cold-expansion process. The fatigue life of coldworked specimens was signitkantly increased compared to non-wldworked ones and increased the !O\ver applied stress level. From a study' nf the residual stress distribution near the edgc of the...

Influence of Residual Stress Field on the Fatigue Crack Propagation in Prestressing Steel Wires

This paper deals with the effect of several residual stress profiles on the fatigue crack propagation in prestressing steel wires subjected to tension loading or bending moment. To this end, a computer program was developed to evaluate the crack front evolution on the basis of the Walker law. Results demonstrate that the absence of residual stresses makes the crack propagate towards a preferent...

Fatigue of Yttria-Stabilized Zirconia: II, Crack Propagation, Fatigue Striations, and Short-Crack Behavior

Fatigue crack propagation in 3Y-TZP was investigated using controlled surface flaws. A unique growth law strongly dependent on the maximum stress intensity factor and quadratically dependent on the amplitude of the range of stress intensity factor was established. This growth law was found to apply for both surface flaws and internal flaws and could be used to predict fatigue lifetime. The pres...

Effect of Stress Ratio on Fatigue Crack Growth Behavior of Magnesium Alloy AZ61 under 3.5 Mass% NaCl Spray Environment*

Fatigue crack growth behavior of AZ61 magnesium alloy was investigated in low humidity (55% relative humidity) and 3.5% NaCl spray environments under various stress ratios. Fatigue crack growth rates became higher with increasing load ratio for both environments. However, the results of fatigue crack growth test under 3.5% NaCl spray environment showed lower fatigue crack propagation rate compa...
