摘要
本文将一个无界区域上的弹塑性问题归结为一个有界区域上的变分不等方程问题,证明了这个问题解的存在唯一性,并证明了这个问题等价于一个鞍点问题。
An elastic-plastic problem in an unbounded domain is reduced to a variational proolem in a bounded domain. The existence and uniqueness of the solution of this variational problem are proved. Furthermore, we show that the variational problem is equivalent to a saddlepoint problem.
