摘要
杂交应力模式的单元在近年来得到了广泛的研究和应用、本文由古典的最小余能原理出发,给出了杂交应力公式导出的完整过程.
The element formulations for hybrid stress model have gained increased popularity in recent years. In this paper a complete derivation of hybrid stress formulation is given from a modified version of principle of minimum complementary energy.
