2D heat conduction of layered composite model

Click For Summary
SUMMARY

The discussion centers on formulating a 2D heat conduction model for layered composite materials, specifically using a finite element approach. The user seeks guidance on creating nodes and assigning varying material properties across layers, having previously worked with 1D conduction models. A suggestion is made to consider the finite difference method as an alternative to finite element modeling for this application. The conversation emphasizes the importance of accurately defining material properties and temperature profiles for effective modeling.

Hi, I am trying to formulate a 2D model to calculate the temperature change over time in a composite material.

The material consists of several layers, and is heated from all edges by a known temperature vs time profile.

I was thinking of creating a finite element model.

Can someone point me to a similar example? I have done 1D conduction model before but always with a homogeneous material. Do I just have to create nodes throughout and assign different material properties to each?

I have attached a schematic of what I am trying to describe.

Thanks

To do the problem as you've defined it, then yes, you have to do it pretty much the way you described. I would be more inclined to use finite difference than finite element.

Thanks Chet, I will give it a try with finite difference method.
