摘要
正交各向异性夹层板的弹性弯曲方程为四阶偏微分非齐次方程组,很难得到函数式解答,只能寻求数值解法。利用差分法建立了差分方程,并通过具体算例比较,误差在允许范围内。
It is very difficult to get the analytic solution of elastic flexure differential equation of orthotropic sandwich slab, and only numerical solution can be obtained. In this paper, finite difference equation is established, and examples show the error is in the allowable range.
