受集中力作用简支椭圆板的上限解

An Upper Bound Solution for a Simply Supported Elliptical Plate Bearing a Convergent Load

摘要: 给出了简支椭圆板在对称轴上任一点处作用集中力的塑性极限载荷的上限解.前人所得的集中力作用在椭圆焦点、椭圆中心的椭圆板问题及集中力偏心作用的圆板等问题均为本文解答的特例。

Abstract: Presents an upper bound solution of plastic limiting load for a simply supported elliptical plate which bears a convergent load on axis of symmetry. Many related solutions can be treated as special cases of this solution.
