On a finite element approximation for the elastoplastic torsion problem
Abstract:
This study is concerned with the elastoplastic torsion problem and its standard finite element approximation using piecewise affine Lagrange finite elements. In the case of a polytopal convex domain in dimension n = 1, 2, 3 we obtain an $H^1$-error bound of order h for the solution. For a nonconvex domain, we obtain also an error estimate.
