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.

An explicit time integration technique for dynamic analyses
International Journal for Numerical Methods in Engineering, 1995AbstractA 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.

Implicit-Explicit Time Integration in Multibody Dynamics
Volume 6: 5th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A, B, and C, 2005Robust and efficient time integration methods in multibody dynamics are tailored to the specific structure of the equations of motion. In the present paper we discuss the combination of explicit methods for non-stiff solution components with implicit methods for stiff solution components and constraints.

Comparisons of Structure-Dependent Explicit Methods for Time Integration
International Journal of Structural Stability and Dynamics, 2015Chang explicit method (CEM)1,2and CR explicit method3(CRM) are two structure-dependent explicit methods that have been successfully developed for structural dynamics. The most important property of both integration methods is that they involve no nonlinear iterations in addition to unconditional stability and second-order accuracy.

A New Explicit Time Integration Scheme for Nonlinear Dynamic Analysis
International Journal of Structural Stability and Dynamics, 2016An explicit time integration method is presented for the linear and nonlinear dynamic analyses of structures. Using two parameters and employing the Taylor series expansion, a family of second-order accurate methods for the solution of dynamic problems is derived.

Explicit time integration with enhanced stability for structural dynamics
Computers & Structures, 1988A new nonlinear explicit method is proposed for structural dynamics. The method retains the computational efficiency of traditional explicit techniques, but possesses better stability properties. Both unpartitioned and partitioned forms of the algorithm are considered.

Improving explicit time integration by modal truncation techniques
Earthquake Engineering & Structural Dynamics, 1998This 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.
