【Abstract】 A new scheme of time stepping for solving the dynamic viscoelastic problems are presented. By expanding variables at a discretised time interval, FEM based recurrent formulae are derived. A self_adaptive algorithm for different sizes of time steps can be carried out to improve computing accuracy. Numerical validation shows satisfactory performance.更多还原
