Critical resistance for multi-phase composite materials
The effect of interfacial resistance on the effective conductivity of a multi-phase composite material was studied. The composite under study is composed of a matrix surrounding different types of circular cylinders arranged in rectangular order. It was assumed that the interfacial resistance is concentrated on the surface of the cylinders. For any direction of calculating the effective conduct...
متن کاملMulti-functional Energy Storage Materials
Hydrogen is recognized as a potential and extremely interesting energy carrier, which can facilitate efficient utilization of unevenly distributed renewable energy. Furthermore, hydrogen has an extremely interesting chemistry and form compounds with most elements in the periodic table and with a variety of different types of bonds. Metal hydrides has recently become very interesting as new clas...
متن کاملVariational convergences of dual energy functionals for elastic materials with a thin strong inclusion
We give a new derivation, based on the complementary energy formulation, of a simplified model for a multi-structure made up of two anisotropic hyper-elastic bodies connected by a thin strong material layer. The model is obtained by identifying the Mosco-limit of the stored complementary energy functional when the thickness is of order ε and the stiffness of order 1/ε where ε is a positive real...
متن کاملWeighted Energy-dissipation Functionals for Gradient Flows
We investigate a global-in-time variational approach to abstract evolution by means of the weighted energy-dissipation functionals proposed by Mielke & Ortiz [MO08]. In particular, we focus on gradient flows in Hilbert spaces. The main result is the convergence of minimizers and approximate minimizers of these functionals to the unique solution of the gradient flow. Sharp convergence rates are ...
متن کاملEnergy functionals for Calabi-Yau metrics
We identify a set of “energy” functionals on the space of metrics in a given Kähler class on a Calabi-Yau manifold, that are bounded below and minimized uniquely on the Ricci-flat metric in that class. Using these functionals, we recast the problem of numerically solving the Einstein equation as an optimization problem. We test this strategy using the “algebraic” metrics (metrics for which the ...
