| 摘 要： | 本文给出一种计算粘弹性结构动力响应的有限元方法，首先根据粘弹性理论导出增量形式的松弛型积分本构方程，然后由功原理导出粘弹性动力学有限元增量方程，最后用逐步积分法计算了３个算例，所得结果与文献结果十分吻合。

| Abstract: | This paper presents a method for finite element analysis of dynamic response in viscoelastic structures. At first,based on the viscoelastic theory,the relaxed integral constitutive relation is given in incremental form,and then the finite element incremental equation of viscoelastic dynamics is derived from the principle of virtual work. Finally,three examples have been showm by use of the successive integral method,and the results coincide with that given by the references very well. |
