## Abstract A variational inequality with uncertain coefficients, which are given in certain bounded intervals, is considered. The inequality corresponds to a torsion problem of an elastoβplastic orthotropic bar, when employing the HaarβKΓ‘rmΓ‘n principle. Two maximization problems with respect to th

This article discusses a general framework for the analysis of initial/boundary-value problems of rate-independent finite elasto-plasticity based on the theory of Green and Naghdi. A constitutive model is developed within the context of the above theory employing generalized measures of Lagrangian s
We proposed some numerical methods for the automatic proof of existence of solutions for some unilateral problems. In this paper, our goal is to establish a new procedure for numerical verification of some unilateral problems. (~) 2000 Elsevier Science Ltd. All rights reserved.
