| Summary: | This paper is devoted to the modeling of finite deformations of
elastic bodies under contact/impact conditions. In this kind of
applications, it is well known that the total energy will be
reduced versus time because of frictional effects. However, how to
identify the dissipated energy in a quantitative way remains an
open question. The aim of this work is to propose a numerical
solution to this question. The proposed Bi-First algorithm
combines the bi-potential method for contact modeling in dynamic
cases and the first order algorithm for integration of the
equation of motion. Numerical examples involve the impact of an
elastic plate onto a rigid surface and the impact between two
hyperelastic blocks and a rigid wall. The dissipated energy versus time will be
plotted and the influence of friction coefficient on the
dissipated energy will be discussed. |
