An explicit time integration scheme for the analysis of wave propagations

Computers and Structures, 2013
A new explicit time integration scheme is presented for the solution of wave propagation problems. The method is designed to have small solution errors in the frequency range that can spatially be represented and to cut out high spurious frequencies. The proposed explicit scheme is second-order accurate for systems with and without damping, even when ...

An Explicit Time-Integration Method for Damped Structural Systems

Structural Engineering and Mechanics, 1995
A damped trapezoidal rule method for numerical time-integration is presented, and its application in analyses of dynamic response of damped structures is discussed. It is shown that the damped trapezoidal rule method has features that make it an attractive approach for applications in dynamic analyses of structures.

Interprocessor communication for high performance, explicit time integration

Engineering with Computers, 2010
Parallel, explicit finite element analysis is based almost exclusively on point-to-point interprocessor communication. However, point-to-point communication on multicore architectures results in large performance variability because of shared caches and sockets.

Stability of explicit‐implicit mesh partitions in time integration

International Journal for Numerical Methods in Engineering, 1978
AbstractThe stability of time integration for a semidiscretization of structures and continua where the mesh is partitioned into subdomains integrated simultaneously by explicit and implicit methods is considered. Stability in energy is proven for linear systems subject to the Courant condition in the explicit subdomain for a central difference ...

Effects of geometric nonlinearities on explicit time integrators

Communications in Applied Numerical Methods, 1988
AbstractThe effect of follower forces and initial stresses on the stability of the central difference method is studied. As a model, bar and beam elements are considered by means of the element eigenvalue inequality. It is shown that both follower‐force pressure loads and tensile initial stresses decrease the stable timestep but the decrease becomes ...

A Comparative Study of Implicit and Explicit Composite Time Integration Schemes

International Journal of Structural Stability and Dynamics, 2020
In this paper, a number of recently proposed implicit and explicit composite time integration schemes are reviewed and critically evaluated. To give suitable guidelines of using them in practical transient analyses of structural problems, numerical performances of these schemes are compared through illustrative examples.

A NEW EXPLICIT TIME INTEGRATION METHOD FOR STRUCTURAL DYNAMICS

International Journal of Structural Stability and Dynamics, 2013
A family of new explicit time-integration method is proposed herein, which inherits the numerical characteristics of any existing implicit Runge–Kutta algorithms for a linear conservative system. Based on an exact derivation of the increment of mechanical energy, the method proposed is demonstrated to be unconditionally stable.

An explicit time integration technique for dynamic analyses

International Journal for Numerical Methods in Engineering, 1995
AbstractA simple explicit solution technique for problems in structural dynamics, based on a Modified Trapezoidal rule Method (MTM) approximation of the governing ordinary differential equations, is developed. The resulting conditionally stable explicit method (MTM) can be easily implemented and is extremely simple to use.
