摘要: 本文讨论粘弹性半空间地基上粘弹性圆板受轴对称载荷时的动力响应,将问题化为在Laplace变换空间中的第一类Fr积分方程,通过数值解和进行数值逆变换求得问题的解答。Abstract: In the present paper, the dynamic problem of a thin viscoelastic circular plate under axisymmetrical load resting on a viscoelastic half-space foundation is discussed. This problem is rnduced to a Fredholm integral equation of the first kind in the Laplace transformation space and solved by numerical procedures. The results of the problem is obtained by taking the numericai Laplace transform inversion.
