A Solution of Variational Inequalities and A Priori Error Estimations in Contact Problems with Finite Element Method

접촉문제에서의 변분부등식의 유한요소해석과 A Priori 오차계산법

Governing equations infrictional contact problems are introduced using variational inequality formulations which are regularized to overcome the diffculties of non-differentiability of the friction functional. Also finite element approximations and a priori error estimations are derived based on those formulations. Numerical simulations are performed illustrating the theoretical results.
