摘要
本文研究球形弹丸对四边简支矩形靶板的冲击问题。应用广义 Meyer 定律,在弹塑性范围内讨论弹丸对靶板的冲击力,将冲击力的求解归结为一个二阶齐次非线性常微分方程的初值问题,采用Runge-Kutta 法对该方程做了数值计算,结果令人满意。
In the present paper,the problem,a rectangular plate having all ends simply sup- ported is impacted by a sphere in the low velocity,is studied.The generalized Meyer law is applied to discuss the contract force between the sphere and the plate in elastiop- lastic case.Thus a homogeneous nonlinear differential equation of the second order is obtained,which has then been solved by the Runge-Kutta method approximately.The results are satisfactory.
