IDEALLY PLASTIC STRESS STATE OF A SOLID NEAR A SPHERICAL CAVITY

In the setting of [1, 2], we consider a perturbed stress state of a hollow sphere of ideally plastic material under the assumption of complete plasticity [3], i.e., under the assumptions that the stress state corresponds to an edge of the Tresca prism. In this case, the problem of the theory of ideal plasticity is statically determinate.
