| Abstract: |
| Direct integration methods are effective methods in solving dynamic equation.This paper applied a predictor-corrector scheme based Generalized-α method for nonlinear structure dynamic equation,and compared it with Newmark method and Bathe method.In this method,the solution of the current computational step is firstly predicted;then,the nonlinear iteration is performed by initializing the solution with the predicted value;the solution is corrected until convergence condition is met,and than the calculation entered the next time step.The method guarantees the performance of Generalized-α method;at the same time it simplifies the nonlinear iterations and is easy to implement.Finally,the examples with large deformation shell and solid elements show the proposed method is stable and accurate. |
