Amir, Muhammad and El Sayed, Tamer (2012) Ultrasonic assisted manufacturing processes : variational model and numerical simulations. Ultrasonics, 52 (4). pp. 521-529. ISSN 0041-624X (https://doi.org/10.1016/j.ultras.2011.11.004)

Abstract

We present a computational study of ultrasonic assisted manufacturing processes including sheet metal forming, upsetting, and wire drawing. A fully variational porous plasticity model is modified to include ultrasonic softening effects and then utilized to account for instantaneous softening when ultrasonic energy is applied during deformation. Material model parameters are identified via inverse modeling, i.e. by using experimental data. The versatility and predictive ability of the model are demonstrated and the effect of ultrasonic intensity on the manufacturing process at hand is investigated and compared qualitatively with experimental results reported in the literature.
