Elastoplastic contact problems with friction Inequalities simplified proof
A) A l,[link widoczny dla zalogowanych], (21) type as dl = a rd \22) mod,[link widoczny dla zalogowanych], with dF,[link widoczny dla zalogowanych], llTI a Tlld \When ll <... when, (1l-...) 0 - the same can prove (21) satisfies the boundary conditions of friction (6.2), we (6.3) type. Need: proof of reference [3]. 4 Conclusion In this paper, bound with a plastic friction contact problems using generalized variational principle of vector analysis tool for a rigorous proof, because they are not non-linear functional analysis and convex analysis, simplifying the certification process. In fact, this method is not difficult to be extended to other forms of generalized variational principle of the proof. [1 - [2: [3] E4] [5] [6] References chang. Generalized variational principle.
