A clear criterion is established for the well-posedness of the initial, boundary, and initial-boundary value problems when the plasticity theory is associative as well as non-associative. The authors show cases where non-associativity leads to ill-posedness of these problems, even when the material is not at failure. Specifically, they demonstrate that the initial-boundary and boundary value problems either have no solution or, if they do, the solution is not unique.
