Influence of spectrum loading on fatigue resistance of AA6082 friction stir welds

J.D. Costa, J.A.M. Ferreira, L.P. Borrego

Welded components are often subjected to variable amplitude service loads, increasing the uncertainty of fatigue life due to material strength, notch geometries, defect content…

Finite element analysis and comparison of laser shock peening and shot peening processes

Goran Ivetic

The aim of this paper is to give a simple and accurate tool for prediction and comparison of residual stresses in laser shock peened and shot peen treated materials.
