摘要:

本文考虑一类抽象的依赖时间的拟变分-半变分不等式,涉及历史依赖算子和一组单侧约束。首先,利用自反Banach空间中椭圆变分-半变分不等式的最新结果,结合历史依赖算子的不动点原理,建立了解的存在性与唯一性。然后,应用该抽象结果证明了拟静态黏弹性摩擦接触问题的唯一弱可解性。接触定律包含针对法向速度的单侧Signorini型条件和非单调法向阻尼响应条件,而摩擦条件是Coulomb干摩擦定律的一个版本,其中摩擦界依赖于累积滑移。

英文摘要:

In this paper we consider an abstract class of time-dependent quasi variational-hemivariational inequalities which involves history-dependent operators and a set of unilateral constraints. First, we establish the existence and uniqueness of solution by using a recent result for elliptic variational-hemivariational inequalities in reflexive Banach spaces combined with a fixed-point principle for history-dependent operators. Then, we apply the abstract result to show the unique weak solvability to a quasistatic viscoelastic frictional contact problem. The contact law involves a unilateral Signorini-type condition for the normal velocity and the nonmonotone normal damped response condition while the friction condition is a version of the Coulomb law of dry friction in which the friction bound depends on the accumulated slip.
