| Abstract: | The adaptive finite element method in structure dynamic analysis is mainly used to study the error estimation in finite element dynamic analysis and establish adaptive finite element mesh generation procedure for dynamic analysis of complex structure. In this paper, the authors first review the important development in dynamic problem of structure by adaptive finite element method, including error estimation and adaptive strategy for the analysis of the free vibration and dynamic response to the external loading. Several present schemes of mesh generation are briefly described. Finally, the existing problems and future trends are discussed. |
