摘要
本文为扩大动态有限单元法的应用范围,在 J.S.Przemieniecki 和 K.K.Gupta 等人的研究基础上建立了一种新的三维动态八结点单元,并对其进行了理论推导。通过算例验证了本文理论结果的正确性。
In order to expand the application field of the finite dynamic element method,a new three-dimensional hexahe-dral finite dynamic element is established and its theoretical deduction is carried out in this paper,based on the studiesby Prazemieniecki and Gupta etc.And a numerical example is giver to verify the correctness of the results of the theo-retic deduction.
