This paper presents a simulation study of the phenomenology arising from plasma expansion between the confinement layer and the base material, which is specifically addressed as a clear factor that influences the subsequent thermo-mechanical behaviour of the treated specimens. Results based on the calculation model show that a number of process scaling laws have been obtained, which allow a predictive...
Laser shock micro-forming is intended as a non-thermal laser forming method using the shock wave induced by laser irradiation to modify the curvature of microscopic scale components. In the present paper, coupled experimental and numerical results are presented showing the influence of different process parameters (target geometry, clamping, laser spot position, laser energy, overlapping of laser...
Laser systems have been widely applied in the last 20 years in semiconductor industry in microfabrication process development, the current availability of new excimer and diode pumped solid state lasers (DPSS) sources are broadening the applications fields of laser microprocessing. Nowadays MEMs, fluidic devices, advanced sensors and biomedical devices and instruments are among the most promising...
Laser shock processing has been proposed as a competitive alternative technology to classical treatments for improving fatigue and wear resistance of metals, and has more recently been developed as a practical process amenable to production technology. For this reason, a decided attempt has been envisaged on the line of the numerical predictive assessment of the effects induced by the LSP technique...
