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...
متن کاملA 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...
متن کاملResidual Stress Effects in Tubular K-joints Crack Growth
Seeking light and transparent bridge designs, engineers and architects have found an efficient and artistic way to fulfill their requirements: steel tubular bridges. Like any other welded structure, the joints of this kind of bridge suffer from high tensile weld residual stresses. Combined with high stress concentrations, tensile residual stress is a relevant factor in fatigue crack development...
متن کاملInfluence 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...
متن کاملFatigue Crack Growth in Adhesive Joints
Adhesive joining is recognized as a potential enabling technology for a variety of material systems being considered in automotive structures where traditional fastening methods would be inappropriate. Well known examples include fiber reinforced composites and polymers. Additionally in certain circumstances, adhesive bonding of steel structures can provide benefits such as improved stiffness a...
