The paper is concerned with radial solutions to the elastic-plastic torsion problem, assuming the free term to belong to Lp(Ω). In particular, we obtain a necessary and sufficient condition in order that the plastic region exists and we characterize the free boundary. Moreover, we find the explicit radial solution u ∈ W2,p(Ω) and the Lagrange multiplier µ-∈ Lp(Ω).

Abstract
The paper is concerned with radial solutions to the elastic-plastic torsion problem, assuming the free term to belong to Lp(Ω). In particular, we obtain a necessary and sufficient condition in order that the plastic region exists and we characterize the free boundary. Moreover, we find the explicit radial solution u ∈ W2,p(Ω) and the Lagrange multiplier µ-∈ Lp(Ω).File in questo prodotto:
