A two-dimensional model for sensitivity studies on laser-generated ultrasound

International audienceA two-dimensional simulation model is presented that, within certain limitative assumptions, calculates the displacements generated by the absorption of a laser pulse in the thermoelastic regime. This model solves the Christoffel equations in an axisymmetrical configuration (the laser excitation is supposed to have a gaussian surface profile) over an infinite plate of finite thickness presenting a cylindrical orthotropy. The resolution of these Christoffel equations is made in the Laplace and Hankel spaces. After the validation of this model by the confrontation of its predictions to experimental data, we present two applications of it concerning the related temporal convolutions occurring to produce the longitudinal precursor
