摘要
本文通过拉普拉斯变换,将最小二乘法应用于薄板的塑性动力响应问题。文中分别以承受均布冲击荷载(中载情形)的简支圆板和方板的塑性动力响应问题为例,说明本文方法的计算方法及步骤,并显示出本文方法的优越性。
In this paper, the least square method is applied to treat the plastic dynamic response of thin plates through Laplace transformation.Two examples of plastic dynamic response of circular and square plastes with simple supported edges under uniform distributed impact loading(middle loading) are given. It shows that the calculation method and procedure proposed by us are good.
