Simulation of dynamic instabilities during high rate deformation of ductile bars and plates

University dissertation from Division of Mechanics, Lund University

Abstract: In this thesis, some of the phenomena occurring in plates and cylindrical bars subjected to dynamic loading are investigated. Numerical simulations using a dynamic finite element code are performed for a number of different sized specimens with various initial surface imperfections. Typically imposed loading velocities are in the range 10m/s
