      We examine elastic-plastic bodies impacting deformable and rigid targets with velocities ranging from 130 tens to hundreds m/sek. The Lagrange expilicit tinite-element method is used to solve the problem. For a number of problems, our results are compared with those obtained from other calculations.
      The problems described have the following i important features: strong deformation, 3-D motion due to impacts, contact surface formation and elimination (variability) on interacting bodies.
