DYNAMIC DEFORMATION OF COMPOSITE PLATES IMPACTING ON RIGID BODIES

Abstract

A methodology for numerically analyzing problems of dynamic deformation of composite plates impacting with low velocities on perfectly rigid bodies is presented. The adequacy of the approach is demonstrated using the analysis of the problem of contact interaction between a steel ball and a composite plate. The influence of various parameters (velocity and mass of the striker, package structure) on the value of the contact force and the deflection in the centre of the plate is analyzed.

Key words: composite materials, low-velocity impact, numerical methods.
