| Abstract: | A simple and computationally efficient adaptive finite 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 refinement enables the finite element mesh to be obtained automatically and the refined meshes influence the calculated contact force. Velocity and mass of impactor has some influence on discretization error as the discretization error changes with the change of these parameters. |
