An Improved Time Integration Method Based on Galerkin Weak Form with Controllable Numerical Dissipation

Based on the newly proposed generalized Galerkin weak form (GGW) method, a two-step time integration method with controllable numerical dissipation is presented. In the first sub-step, the GGW method is used, and in the second sub-step, a new parameter is introduced by using the idea of a trapezoida...
