Abstract
Ultrasonic welding is an efficient technique for rivetless assembly of thermoplastic composites. To further improve this process, it is necessary to develop numerical simulations. A phenomenon often misevaluated but crucial for accurate process simulations is hammering. It is the loss of contact between sonotrode and upper adherend during the vibration phase. The goal of this paper is twofold: present an experimental procedure to measure the displacement of the sonotrode and upper adherend during welding, and discuss two strategies to quantify amplitude transmission to the upper adherend. This will lead to improvement of predictive models for ultrasonic welding and closer agreement with experimental data.
