Une condition aux limites simple pour les problemes non bornes
Keywords:
finite elements, unbounded domain, elasticity, potential problemsAbstract
We describe a new and simple boundary condition, which can be used in the finite element analysis of static unbounded problems of elasticity and potential. From the classical series solutions in two and three dimensions of Laplace's equation, we develop a set of appropriate boundary conditions and using them as boundary conditions on the exterior of a finite element mesh. We present some results in two and three dimensions for elastic problems.
