Abstract

Abstract: A signorini problem with Coulomb friction in a kind of elasticityplasticity theory is considered. We prove the existence and uniqueness of the solution to this problem with small friction.

Key words: Elliptic systems, variational inequalities, elasticityplasticity, signorini problems, friction

摘要： 考虑了某类弹塑性理论中带有摩擦的Signorini问题。设摩擦遵从Coulomb定律。证明了在摩擦系数适当小的条件下，该问题的解存在唯一。
