Numerical investigation of contact/impact problems between deformable bodies

Abstract : The bi-potential method has been successfully applied to the modelling of frictional contact problems in static cases. This paper presents the extension of this method for dynamic analysis of impact problems. A first order algorithm is applied to the numerical integration of the time-dicretized equation of motion. The solution algorithm is simple and efficient. Two numerical examples are carried out in 2D: a longitudinal elastic impact between two slender bars and a more complex impact between two cylinders inside rigid walls.
