Simulating Thermal Conctact Resistance in Mechanica

Simulators,

Has anyone had experience modeling thermal contact resistance using
Mechanica? Is it possible to handle this phenomena using Mechanica?
Integrated or independent mode? Face-face contact or some type of
multi-type element black magic (e.g. bar/beam connections)? I am
interested in hearing about both successful or unsuccessful experiences.

Thanks in advance for anything you are willing to share.

Michael

Re: Simulating Thermal Conctact Resistance in Mechanica

Michael,

Thermal Contact Resistance can be modeled using a thin layer of solid
elements at the interface. You simply adjust the ?K? value to be
proportional to the ratio of solid-to-solid contact versus the
solid-to-air-to-solid contact.

The ?K? value can be varied using a MECHANICA Design Parameter,
allowing you to study the downstream effects of differing levels of
contact resistance using Sensitivity Studies.

It?s quite easy to implement, just be careful of getting the layer too
thin because of meshing limitations with high aspect ratio (really
thin elements).
