This paper introduces a fully implicit partitioned coupling scheme for problems of thermoelasticity at finite strains utilizing the p-version of the finite element method. The mechanical and the thermal fields are partitioned into symmetric subproblems where algorithmic decoupling has been obtained by means of an isothermal operator-split. Numerical(More)
We present a detailed analysis of the convergence properties of the finite cell method which is a fictitious domain approach based on high order finite elements. It is proved that exponential type of convergence can be obtained by the finite cell method for Laplace and Lamé problems in one, two as well three dimensions. Several numerical examples in one and(More)
Open-­‐cell aluminum foams represent an important class of core materials that are used to manufacture lightweight sandwich-­‐structured composites. A nickel coa9ng applied by electro-­‐deposi9on can further improve their proper9es. In order to characterize these hybrid metal foams, we perform a full resolu9on computa9on BLOCKIN BLOCKIN of BLOCKIN BLOCKIN(More)
