But this process implies distortion and high internal stresses, which affect the service life of products, due to the high temperature gradient. The simulation allows minimizing those effects by helping for the selection of the good geometry, material and process parameters without a lot of costly experimental tests. However, the development of a good simulation tool for the laser welding requires understanding the short-time metallurgical processes due to the very high heating rates, as it has a direct influence on the material law. A method using the knowledge of metallurgical processes is proposed to require less experimental tests to build the material law database for the simulation model. In this aim, some experimental tests on a bainitic 100Cr6 were carried out. Dilatometer tests to high heating rates and then, metallographic observations on the heating specimens are made to determine the material microstructur...

A methodology to study the behaviour of delaminated composite structures has been developed. This study can be split up into two parts. The first is about the detection of delamination in damaged laminated thin structures. In the finite element computational code used, those laminated structures are modeled using shell
