文摘

This article is devoted to the modeling of finite deformations of hyperelastic bodies under contact/impact conditions. A total Lagrangian formulation is adopted to describe the geometrically nonlinear behavior. A first order algorithm is applied to integrate the equations of motion. The contact problem is solved by the bi-potential method. For the finite element implementation, an explicit expression of the tangent operator for the e6271012ab6""> hyperelastic model is derived. The classical Boussinesq–Love contact problem is first investigated numerically. A second example concerns the impact between two hyperelastic bodies in three-dimension. To cite this article: Z.-Q.
