Calculation and Analysis of Artificial Boundary with Substructure Condensation Element

Abstract:

Artificial boundary is an important part of finite element calculation model. Based on finite element method, this paper presents substructure condensation elements to simulate far field boundary. As most dynamic responses are focused on ground surface, substructure elements’ internal nodes are condensed and only keep the nodes on the ground surface to maintain the accuracy of scattering wave transmition. According to the example of verification, if the related parameters are chosen properly, the effect of substructure condensation boundary is guaranteed.
