摘要：

An algorithm based on the generalized time finite element method (GTFEM) for the integration of a dynamic equation for a nonlinear problem is considered. It involves two free parameters, θ1 and θ2, which are optimized with respect to accuracy and computational effort. The results for the proposed scheme are evaluated and compared with commonly used Newmark and Wilson procedures. © 1987.
