Ansys: Heat due to Friction

I am doing my B.Tech Project on Finite Element Analysis. I need to generate the following thing in Ansys - One body slides over another and due to friction, heat is generated.

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution

Re: Ansys: Heat due to Friction

If you have a stationary object and another is rubbed on it heat is generated. The heat generated equals the work done. The work in ft-lbs can be directly equated to BTU's by dividing the ft-lbs by 778. The work done is frictional force times distance.

Hi Lawrence,

That is true but that is not what I am looking for. I need someone to explain the procedure to simulate this in Ansys. I am trying a lot in vain. Please help me out :(

Re: Ansys: Heat due to Friction

Unfortunately in my career with a chemical company, I did not use ANSYS. So I am afraid I cannot help you. I did a considerable amount of work with FE but it was in the area of heat transfer and stress analysis. For stress problems I used NASTRAN and SDRC softwares.

On the lighter side, objects sliding on one another and heating is frowned upon in the chemical industry.

Hopefully you can find an instruction manual for ANSYS. It is very powerful software.

Oh okay.
If someone can please explain me a detailed procedure of doing the problem in vm229 (verification manual) of Ansys 11 or 12, it will be really helpful.
