Paper Abstract

Although significant work has been conducted in order to explore the optimum conditions of application of LSP treatments and to assess their capability to provide enhanced mechanical properties, only limited attempts have been developed in the way of predictive assessment of the characteristic physical processes and transformations with a specific consideration of the associated laser interaction dynamics. For this reason, additionally to the authors' efforts in the line of the numerical predictive assessment of the effects induced by the LSP technique from a predominantly mechanical point of view, the observation and analysis of the plasma dynamics following laser interaction have been envisaged as a means for the proper assessment of the shocking process relative to the material target and also as a way of plasma dynamics control in view of process optimization. In the present paper, the basis for the plasma spectroscopic observation of LSP experiments in combination to numerical dynamics simulations are proposed as a means for the extraction of relevant guidelines for process design optimization.
