摘要
给出了用于求解结构动力响应的基于不协调时间有限元方法的算法公式，以及采用三次Hｅｒｍｉｔｅ插值多项式逼近状态变量。应用时间不连续的Ｇａｌｅｒｋｉｎ方法推导出的一个单步递推新算法公式。同时给出了与Ｎｅｗｍａｋ的梯形法则、ＨＨＴ－α等几种算法的数值比较。
This paper presents an algorithm formula of finite element methods according to incoordinate time for the solution to structural dynamics response. and a new algorithm formula of single step recurrence by the approach of incontinuous method of Galerkin and by applying the method of approaching state variable with interpolation polynomical three times. It also makes a detail comparison of number between the Newmak trapezoidal rule. HHT-a algorithm. etc.
