Numerical Study of the Effect of Materials’ Plastic Behavior on Equibiaxial Residual Stress Measurement Using Indentation

Indentation is a new method for estimating residual stress. The plastic behavior of the materials under study can affect indentation parameters and, thus, influences the results of residual stress measurement. In this paper, the effect of yield stress and work-hardening exponent on the accuracy of residual stress measurements in steels and aluminums was studied. Results showed that, for m...

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...

Coating thickness effect on stress distribution of coated cylinder head considering residual stress

This paper presents the coating thickness effect on the stress distribution of a coated cylinder head. A typical thermal barrier coating was applied on a diesel engine cylinder head. Thus, the residual stress which occurred during the plasma thermal spraying was also considered. The coating system consisted of two layers a metallic bond coat and a ceramic top coat. The bond coat thickness is co...

Relation between Residual Stress and Fatigue Strength for Electron Beam Welded Joints of Sheet Metal

Residual stresses in welds significantly affect the fatigue strength and stress corrosion crack resistance of the weld joint, and therefore, numerous studies have been made about the effects. The residual stress induced by electron beam welding (EBW) has also been researched in various approaches, but many of the study reports dealt with thick plates (50 mm or thicker) only.1–5) This was becaus...
