| Abstract: | 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. |
