✦ Synopsis


In this Note we present a model for an unsteady pure traction problem in large displacement and small perturbation for an elastic body in dimension 2, and we show the existence of a solution to the associated problem. The weak formulation of this nonlinear problem involves test-functions depending on the solution, which is not standard. We then study the dynamic of the translation, of the rotation, and of the perturbation associated to the deformation of the body. We prove the existence of a weak solution using a Galerkin method.

## Abstract This paper illustrates the application of Wynn's vector ε‐algorithm to solve a system of equations arising in the method of moments (MoM) solution of an electrostatic problem. Since the method is iterative, it does not require inversion of a matrix. The degree of accuracy of the solutio
