平衡力和应力的广义应力集中系数
Generalized Stress Concentration Factors for Equilibrated Forces and Stresses
摘要：
作为最近的工作的续集，我们考虑广义应力集中系数，一个纯粹的几何性质的一个机构，为各种外部负载字段表示最大的最佳应力和最大的外部负载之间的最坏的比率。最佳应力集中系数与满足虚功原理的应力场有关，并且应力集中系数最小。与以前的工作不同，我们要求外部载荷平衡，应力场是对称张量场。
英文摘要：
As a sequel to a recent work we consider the generalized stress concentration factor, a purely geometric property of a body that for the various external loading fields indicates the worst ratio between the maximum of the optimal stress and maximum of the external loading. The optimal stress concentration factor pertains to a stress field that satisfies the principle of virtual work and for which the stress concentration factor is minimal. Unlike the previous work, we require that the external loading be equilibrated and that the stress field be a symmetric tensor field.
