An Improved Semi-Implicit Method for Structural Dynamics Analysis
Copyright policy )An Improved Semi-Implicit Method for Structural Dynamics Analysis
A semi-implicit algorithm is presented for direct time integration of the structural dynamics equations. The algorithm avoids the factoring of the implicit difference solution matrix and mitigates the unacceptable accuracy losses which plagued previous semi-implicit algorithms. This substantial accuracy improvement is achieved by augmenting the solution matrix with two simple diagonal matrices of the order of the integration truncation error.
