Abstract
Laser surface treatments induce, like any other surface treatment, thermal gradients and hence residual stresses. In the present work, these stresses are determined in the case of coatings of various metallic materials on two different substrates: a low carbon steel and an austenitic stainless steel. Qualitative analysis of experimental results is performed by using a phenomenological modelling based on a decomposition of the specimen into three different parts. A generalization is proposed, which allows simple predictions of the behaviour.
