Hi,
My simulation is coupled temp-displacement analysis which consist of two parts.
Part1 penetrates Part2 and makes elastic-plastic deformation,heat transfer and then detached.
Simulation runs very well.(when i use arbitary contact thermal conductance value)
Problem is that I don't know how to calculate contact thermal conductance.
Could anybody let me know how to calculate that in below condition?
1. thermal conductivity of two parts is A and B respectively
2. contact has perfect contact surface(no voids at the interface, surface waviness, and surface roughness, etc)
3. pressure effect can be ignored.
thanks.
