Modeling of Thermal Joint Resistance of Polymer-metal Rough Interfaces
A compact analytical model is developed for predicting thermal joint resistance of rough polymer-metal interfaces in a vacuum. The joint resistance includes two components: i) bulk resistance of the polymer and ii) micro, constriction/spreading resistance of the microcontacts at the interface. Performing a deformation analysis, it is shown that the deformation mode of the polymer asperities is ...
متن کاملMicromechanics of Rough Interfaces
The mechanical behavior of rough interfaces is modeled from a micromechanical viewpoint. A kinematically driven mechanistic approach is adopted which explicitly considers the interaction of asperities on the fracture surface. The mating asperities are assumed to behave in accordance with contact mechanics postulates of non-conforming bodies. The roughness of the fracture surface is represented ...
متن کاملUsing System Interfaces for Failure Propagation Modeling and Analysis
XXX XXX XX XXX. In this paper we propose a novel approach for safety analysis based on system interface models, which are shared for both system and safety engineering. By extending interaction models on the system interface level with failure modes as well as relevant portions of the physical system to be controlled, automated support can be provided for much of the failure analysis. We partic...

متن کاملWidth of Rough Interfaces on Asymmetric Lattices
I present a calculation of the interfacial width within the capillary wave (Gaussian) approximation. The calculation is done on rectangular lattices of size L1 times L2, with periodic boundary conditions.
