The distinctive features of the collision between an elastoplastic cylinder and a non-deformable obstacle

The distinctive features of the process involving the collision of a elastoplastic cylinder with a non-deformable wall are investigated numerically: the dependence of the dynamics of the interaction on the coefficient of friction between the impactor and the obstacle, the dependence of the final shape of the impactor and the duration of its contact with the obstacle on the initial velocity and length of the cylinder, the distinctive features of the dynamics of the change in the contact area of the impactor and obstacle and of the velocities of motion of the contact discontinuity points, etc. The calculations are carried out in an axisymmetric formulation using the “TIS” original software package in which the method of splitting with respect to physical processes and the finite volume method for moving Euler meshes are implemented.
