The incompressible limit in linear anisotropic elasticity, with applications to surface waves and elastostatics
Incompressibility is established for threeand two-dimensional deformations of an anisotropic linearly elastic material, as conditions to be satis ed by the elastic compliances. These conditions make it straightforward to derive results for incompressible materials from those established for compressible materials. As an illustration, the explicit secular equation is obtained for surface waves i...
متن کاملA boundary element procedure for contact problems in plane linear elastostatics
— Hère we present a new solution procedure for contact problems in plane linear elastostatics via boundary intégral variational inequalities having as unknowns the trace of the displacement field and its boundary traction. We admit the case of only traction-contact boundary conditions without prescribing the displacements along some part of the boundary of the elasticly deformed body. Without i...
متن کاملThe L∞-Stokes semigroup in exterior domains
The Stokes semigroup on a bounded domain is an analytic semigroup on spaces of bounded functions as was recently shown by the authors based on an a priori L∞-estimate for solutions to the linear Stokes equations. In this paper, we extend our approach to exterior domains and prove that the Stokes semigroup is uniquely extendable to an analytic semigroup on spaces of bounded functions.
متن کاملA Fully Discrete BEM-FEM for the Exterior Stokes Problem in the Plane
We reformulate the Johnson–Nedelec approach for the exterior two-dimensional Stokes problem taking advantage of the parameterization of the artificial boundary. The main aim of this paper is the presentation and analysis of a fully discrete numerical method for this problem. This one responds to the needs of having efficient approximate quadratures for the weakly singular boundary integrals. We...
