✦ Synopsis

A simple and computationally ecient adaptive ®nite element analysis strategy has been adopted for accurate and reliable evaluation of contact force under low velocity impact. Contact of a spherical and cylindrical impactor on isotopic plates is considered. Adaptive mesh re®nement enables the ®nite element mesh to be obtained automatically and the re®ned meshes in¯uence the calculated contact force. Velocity and mass of impactor has some in¯uence on discretization error as the discretization error changes with the change of these parameters.

The nature of the response of compact and flexible bodies subject to low velocity impact is studied. The key parameters which govern the response for such impacts are identified and their effects on impact response are examined through numerical simulations. It is shown that three non-dimensional pa
