Analysis of shock calculation based on Newmark integral method

Abstract

In this paper, the time domain method for the calculation of impact resistance is studied. Firstly, the central difference method and the Newmark integration method based on the analysis of the linear equations and the solution of the nonlinear equations are educed. Then, the advantages and disadvantages of these two methods are compared and analyzed, and the conclusion is that the Newmark integral method is suitable for the calculation of the non dynamic equation.
