Ultrasonic Welding of Thermoplastic Composites, Modeling of the Process.

Abstract : The process of ultrasonic welding is widely used in the industry. Nevertheless, its numerical modelling, essential for the aeronautic industry, is quite difficult because of the two time scales present in the process. After explaining principle of the welding, a method of time homogenization is presented in order to write down three different thermal and mechanical systems of equations. Since one of those problems implies moving free surface, a numerical tool using the level-set method was used to solve them.
