非线性弹性杆波动方程的精确解

摘要

Under travelling wave solution assumption the two nonlinear equations transformed to the ordinary differential equations and then using the Exp-function method with aid of Mathematica,the exact solutions of two nonlinear elastic rod wave equations was obtained.%通过假设2个非线性弹性杆波动方程的行波解，得到其常微分方程，运用Exp函数法，并借助Mathematica软件，获得了这2个非线性弹性杆波动方程的精确解。
