Also tell how to handle thermo-mechanical Analysis using FEM in the solid region, when an high energetic beam (may be 1 GeV) is coming and hitting a solid made up of Steel having thickness 3-5 mm. -Arul.

 August 29, 2005, 17:50 Re: Thermo-Mechanical Analysis #2 Ahmed Guest   Posts: n/a This is a heat flux input, you have to convert the 1 GeV to Jouls and when you set your BC's this is the boundary condition heat input flux. Just read the instructions (Help files) of your FEM solver

 August 30, 2005, 06:35 Re: Thermo-Mechanical Analysis #3 K. Arul Prakash Guest   Posts: n/a I am not using any packages for solving this problem. I need constitutive relations used to solve this type of problem. I want to develop my own FEM solver.

To be frank whether you really understand the question which I asked and the gravity of the problem..You are talking regarding conduction problem (even a school student can solve this regardless of science or engineering degree). First read the question carefully before answering anything. Its just not giving a reference of some book and telling about degree. If you want to know what the real problem look the book "Introduction to Non-linear ThermoMechanics" by Andrzej Sluzalec, Springer NY and refer chapter 4. page 35-44. If you are really a good academecian means you should teach something you know. Otherwise you should not reply. Don't reply rubbish like this in future however great you should be. we already solved the conjugate problem (I don't know whether you really know this or not). It is Thermo-mechanical analysis.. means we want to solve for both thermal and Mechanical Stress and finally find the total stress. We solved this problem and we are interested to discuss postprocessing.

 September 1, 2005, 13:09 Re: Thermo-Mechanical Analysis #6 Ahmed Guest   Posts: n/a Two days ago you were asking how to apply a boundary condition Yesterday you asked what equation to use, since you plan to write a FEM programme Today you say you have solved the Prolem This is indeed a MIRACLE Keep on the good work

 September 1, 2005, 14:24 Re: Thermo-Mechanical Analysis #7 K. Arul Prakash Guest   Posts: n/a Asking how to handle a thermo-mechanical analysis problem is not meaning how to apply the boundary conditions. Eventhough we solve the problem there is not always a unique way for attacking any problem.(If U are a numerical person U will very well know this). I want to discuss several alternative ways and techniques. U are always meant for a simple conduction problem, which is not the problem I am discussing for. Refer the book I mentioned. Please do not reply if U know exactly know about the problem and waste unnecessarily others time by writing about MIRACLE and DEGREE.. Better you stop discussing.
