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.

An explicit time integration scheme for the analysis of wave propagations
Computers and Structures, 2013A 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 ...

Improving explicit time integration by modal truncation techniques
Earthquake Engineering & Structural Dynamics, 1998 This paper describes a modal weighting technique that improves the stability characteristics of explicit time-integration schemes used in structural dynamics. The central difference method was chosen as the trial algorithm because of its simplicity, both in terms of formulation and ease of numerical stability and convergence analysis.

Stability of explicit‐implicit mesh partitions in time integration
International Journal for Numerical Methods in Engineering, 1978AbstractThe 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 ...

Interprocessor communication for high performance, explicit time integration
Engineering with Computers, 2010Parallel, 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.

A Comparative Study of Implicit and Explicit Composite Time Integration Schemes
International Journal of Structural Stability and Dynamics, 2020In 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, 2013A 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.
