Reliable solution in strain space of elastoplastic problems with isotropic hardening and uncertain data.
Quasi-static problems of the flow theory of elastoplasticity are formulated instrain space by means of a variational inequality. Continuous dependence of the resulting stress tensor on some input data ( coefficients, initial conditi...
