摘要：

This talk consists two parts: For the variational inequalities model obstacle problems, we propose and analyze some numerical algorithms based on some equivalent formulations. The algorithms for the related discrete Hamilton-Jacobi-Bellman equation are also discussed.

The second part concerns a Quasistatic history-dependent contact model. It is a hemi-variational inequalities model. We analyze the finite element methods to approximate it, derive some error estimates and analyze some algorithms. Several models for different contact conditions in hemi-variational inequalities are mentioned.
