3.8.1 Implicit Time Integration Newmark method is a commonly used implicit integration scheme, in which the velocity and displacement at time tn+1 are solved with the use of (3.181)u˙iIn+1=u˙iIn+Δt[(1−γ)u¨iIn+γu¨iIn+1],0⩽γ⩽1, (3.182)uiIn+1=uiIn+Δtu˙iIn+Δ...
Since the publication of the time integration scheme for finite element solutions involving nonlinear large deformations, much additional experience has been gained. As may be expected, the scheme is now widely used for some nonlinear analyses, specifi- cally also in contact solutions, but – ...
For a given accuracy, we investigate the efficiency of higher order time integration schemes compared to lower order methods. In the partitioned FSI simulations on a one-dimensional piston problem, a mixed implicit/explicit (IMEX) time integration scheme is employed: the implicit scheme is used ...

Symmetric formulation of tangential stiffnesses for non-associated viscoplasticity with an implicit time integration scheme 喜欢 0 阅读量: 26 作者:Xiong,Wen-lin 摘要: A numerical scheme is presented which enables the use of symmetric equation solvers in tangential stiffness programs for non-associated...
The use of unconditionally stable implicit time integration techniques for pseudodynamic tests has been recently proposed and advanced by several researchers. Inspired by such developments, a pseudodynamic test scheme based on an unconditionally stable implicit time integration algorithm and dual displacement...
in the framework of additive Schwarz preconditioners. Nevertheless, fully implicit time discretizations allows to avoid constraints on the time steps in order to ensure stability of the numerical scheme. In this perspective, they are more flexible in case time adaptivity is also considered, see e.g...
