摘要
本文提出了一般弹塑性问题增量理论的一种数学等价形式——变分不等式.在材料服从Drucker公设时,证明了这种不等式解的存在唯一性,并讨论了有限元解的收敛性。
In this paper, the incremental theory of an elastic-plastic problem is transformed to a variational inequality. The existence and uniqueness of the variational inequality are proved for the materials in which the Drucker Law is satisfied. And the convergence of the finite element solutions is also discussed.
