Topological FEM method for the analysis of time-varying structures

A topological FEM method, in which a structure topological theory is applied to a FEM system, is presented in this paper. The method uses FEM solutions of a structure before any change to obtain the new response of changed structure, avoids re‐calculations from changing the FEM system, and reduces t...

Zusammenfassung:A topological FEM method, in which a structure topological theory is applied to a FEM system, is presented in this paper. The method uses FEM solutions of a structure before any change to obtain the new response of changed structure, avoids re‐calculations from changing the FEM system, and reduces the amount of calculation work on a large scale. It is a new method for time‐varying calculation in construction and technical analysis. Copyright © 2004 John Wiley & Sons, Ltd.
