本文介绍了简支矩形板弯曲的应力沿板纵向线性变化时求解局部稳定性临界应力的一种实用方法。用能量法验证了该方法,证实该方法可在工程实际计算中推广使用。
This paper presents a practical method for solving the critical stress of local stability when the bending stress of simply supported rectangular plates changes linearly along the longitudinal direction of the plate. The method is validated by energy method, which proves that the method can be used widely in practical engineering calculation.
