The generalized-α method and α-RATTLE method were used in the numerical integration of nonholonomic constrained mechanical systems,i. 将源于直接积分方法的广义-α法和α-RATTLE法应用到非完整力学系统动力学方程数值积分中,直接求解指标-2的微分-代数方程(DAEs),这两种方法的质量矩阵可以是常量,也可以与广...
The method is unconditionally stable and has second-order accuracy in time. We extend the second-order generalized-method to third-order in time while the numerical dissipation can be controlled by a single parameter. In each time step, the scheme only requires inverting one matrix on ...

In this article, the existing nonsmooth generalized‐α method for the simulation of mechanical systems with frictionless contacts, modeled as unilateral constraints, is extended to systems with frictional contacts. On that account, we complement the unilateral constraints with set‐valued Coulomb‐type ...
The present paper shows that the explicit generalized alpha method can be rewritten so that it becomes compatible with the implicit form. All four algorithmic parameters can be matched between the explicit and implicit forms. An element interface between implicit and explicit partitions can be used,...
