Analysis of forces generated in Friction stir welding(FSW) process

Submitted by shashikiran11 on Sat, 04/30/2011 - 12:10

Hey, this is Shashi kiran. I am pursuing post graduation(M.Tech) in NIT Trichy, India.

I have a problem in my project regarding FSW process. I have to analyse the process for forces generated by the rotating tool and verify whether the toggle clamps i used for the process is sufficient to hold the workpiece.

Can anyone help me out in this regard like how to analyse in ANSYS the forces generated, by specifying rotating and traversing speed of the tool?

Hi,

I want to do FE analysis of metal cutting. Is there any governing equation for this problem to solve with FEM.

Thanks and regards.

Last day, I took my class of Nonlinear Analysis of solids and structures.

And I learned about the strong form & weak form in the prilciple of Virtual work.

I can find the origin of those two form that is from Piola-Kirchhoff stress tensor.

but why Integral form is called "weak form"? why Differential form is called "strong form"? why?

I was just wondering.

PhD culture

pedagogy

Dear All,

What do you think is the difference in PhD in Europe, USA? My thesis supervisor used to say "In US it is a deep inspection of a subject, while European PhD is a grand problem solving" What is your opinion on this matter? Is there some basic difference between how a PhD is approached by students and supervisor in both these places? if indeed there is a difference, in your opinion which approach is preferable??
