报告内容简介：
In recent years, modeling, analysis, and numerical solution of hemivariational inequalities have attracted much attention in the research communities. Through the formulation of hemivariational inequalities, application problems involving nonmonotone, nonsmooth and multivalued constitutive laws, forces, and boundary conditions can be treated successfully. Hemivariational inequalities have been successfully applied in a wide variety of subjects, ranging from nonsmooth mechanics, physics, engineering, to economics.

The talk will begin with a brief discussion of a model boundary value problem of an elliptic PDE and sample variational inequalities, and then introduce hemivariational inequalities. A summary account of recent and new results is provided on theoretical and numerical analysis of hemivariational inequalities arising in solid mechanics and fluid mechanics.
