Abstract:

In this paper we deduce by $\Gamma$-convergence some partially and fully linearized quasistatic evolution models for thin plates, in the framework of finite plasticity. Denoting by $\epsilon$ the thickness of the plate, we study the case where the scaling factor of the elasto- plastic energy is of order $\epsilon^{2\alpha-2}$, with $\alpha\geq 3$. We show that solutions to the three- dimensional quasistatic evolution problems converge, as the thickness of the plate tends to zero, to a quasistatic evolution associated to a suitable reduced model depending on $\alpha$.

Keywords: $\Gamma$-convergence, quasistatic evolution, rate-independent processes, thin plates, finite plasticity
