A New Universal Algorithm Based on Integral Quardrature for Dynamic Response

In order to obtain a structural dynamic response,a new universal algorithm is presented.First order differential equation systems are integrated to be dispersed into linear system of equations by Newton-Cores formula.This method is characterized with universal algorithm,3-order precision,no issue of stability.Structural dynamic equation is transferred into first order differential equation systems by state equation.The example result comparison with analytic solution shows this method is reliable and satisfying.
