Topological FEM method for the analysis of time-varying structures

摘要

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.
