Fast numerical estimation of residual stresses induced by laser shock peening

The aim of this paper is to develop a model allowing fast first approximate estimation the elastic–plastic stress wave propagation caused by laser impact and resulting residual field. We start modeling propagation, adopting 1D uniaxial modeling, reducing behavior specimen axis impact, excluding any edge effects edges spot. plastic strain field from can in turn be used compute stresses, making use an analytic case infinite planar plate. accuracy assessed comparing it finite elements simulations, acting as reference solution, for several materials spot diameters. results show that close identical solution. fields present distribution on large portion spot, except very center. comparison between solution shows good match, indicating approximation mechanical created diameters larger than 2 mm.
