Dear All,



Please join the Department of Applied Mathematics for a Research Talk





When: Wednesday, March 22, 2017, 1:50 pm - 2:55 pm

Where: RE 032



*Title: Numerical Analysis of Hemivariational Inequalities*



*Speaker:* *Weimin Han*



*Department of Mathematics*

*University of Iowa*







*Abstract:*  Inequality problems in mechanics can be divided into two main
categories: that of variational inequalities concerned with convex energy
functionals (potentials), and that of hemivariational inequalities
concerned with nonsmooth and nonconvex energy functionals
(superpotentials). Through the formulation of hemivariational inequalities,
problems involving nonmonotone, nonsmooth and multivalued constitutive
laws, forces, and boundary conditions can be treated successfully.
Hemivariational inequalities have been shown to be very useful across a
wide variety of subjects, ranging from nonsmooth mechanics, physics,
engineering, to economics.



In this talk, after a brief description of the basic notions and ideas of
the theory of hemivariational inequalities, we will present new results on
convergence and optimal order error estimates for numerical solutions of
hemivariational inequalities. Numerical results will be presented.







Cookies and coffee will be provided in RE 112 after the talk.
