Reliable solution of a torsion problem in Hencky plasticity with uncertain yield function.

Original language description

The worst scenario method is applied to the torsion problem of a homogeneous orthotropic elasto-plastic bar with uncertain yield function. According to the Haar-Kármán principle, the problem leads to a minimization of the complementary energy over a convex set of admissible stresses. The latter setis determined by a yield function with uncertain coefficients. We formulate two maximization problems with respect to the set of admissible coefficients, prove the solvability of the corresponding continuous and..
