The purpose of the present study is to estimate the weldability of a polymeric material couple according to their thermal and optical properties. A first model based on Mie theory and Monte Carlo method describes the laser beam behavior in semi-trans

Tribological systems are complex systems that require a multi-disciplinary (mechanical, material, physico-chemical) approach where numerous influence factors can be involved. To characterize a contact couple, the intrinsic parameters of the materials

For analyzing the polymers laser grooving, two response functions were chosen: the groove’s width and depth. The study investigates the influence on these functions of the successive number of passes on the same groove direction, by using the analy

From the phenomenological point of view, laser cutting processes are complex, weakly organised and diffuse systems. Offline optimization of such processes demands relative simple, but accurate enough models, which could be obtained byexperimental way
