Abstract
The examination of an unstructured finite volume method for structural dynamics is assessed for simulations of systematic impact dynamics. A robust display dual-time stepping method is utilized to obtain time accurate solutions. The study of impact dynamics is a complex problem that should consider strength models and state equations to describe the mechanical behavior of materials. The current method has several features. 1) Discrete equations of unstructured finite volume method naturally follow the conservation law. 2) Display dual-time stepping method is suitable for the analysis of impact dynamic problems of time accurate solutions. 3) The method did not produce grid distortion when large deformation appeared. The method is validated by the problem of impact dynamics of an elastic plate with initial conditions and material properties. The results validate the finite element numerical data.
