Methodology for modeling of dynamic processes by finite element method - Phase I
Kolman, Radek ; Gabriel, Dušan ; Červ, Jan ; Plešek, Jiří
In the report, the using of explicit finite element analysis for solving wave propagation problems in solids is presented in depth. Its grid and full dispersion analysis is given with the influence of mesh size and time step size. Conclusion of the report summarizes criteria for mesh size and time step size settings so that dispersion errors do not exceed permissible values.
