Towards description of mechanical damage of thin molybdenum film upon pulsed laser irradiation
Original language description
In this work, as a first step, we study the role of stress as a damage mechanism for a thin molybdenum film deposited on a glass substrate and irradiated by an ultrashort laser pulse using two different models: an hydrodynamic model and a thermo-elastic model. Coupled with a two-temperature model (TTM) and an equation of state, the hydrodynamical description enables us to compute the pressure and density of the solid as function of laser irradiation parameters. A Lagrangian approach was adopted to easily determine the laser-induced motion of the free surface. The thermoelastic model, relatively simpler to implement, is based on the two temperature energy balance equations supplemented by an equation tracking the lattice displacement induced by the thermal stress but without accounting for the deformation of the material.
