摘要
本文从计入中面力的薄板控制微分方程出发,导出了求解纵横荷载共同作用下基础板弯曲问题和稳定问题的计算格式,耦合片平面问题和板弯曲问题,有效地解决了复杂荷载作用下板弯曲问题和临界荷载的计算。
Basing on the governing equation of a thin plate on elastic foundation subjected both to the transverse loading and in-plane forces, a formulation of spline BEM for the solution of the bending problem and the buckling load of the plate on elastic foundation has been deduced, which is a coupling of the plane problem of slice and the bending problem of slab with the consideration of the mathematical model of the elastic foundation. Thus, both the bending problem and the b ckling load of the plate on elastic foundation may be solved effectively.
