Discussion of fracture paper #1 - A contol volume model

Submitted by ESIS on

This is a premiere: my first contribution to the new ESIS' blog announced in January. Why comment on papers in a scientific journal after they have passed the review process already? Not to question their quality, of course, but animating a vital virtue of science again, namely discussion. The pressure to publish has increased so much that one may doubt whether there is enough time left to read scientific papers. This impression is substantiated by my experience as a referee.

Forging process simulation

Submitted by vicky_raizada on

Hello friends,

I am doing My Graduation in Mechanical, right now i am on a project and want to simulate Forging cylinderical billets in order to optimise the process parameters, hence it is required to optimize the process parameters like temp., speed , stroke, material flow etc. as a function of Die design and friction. I want to simulate it in ANSYS plz help me how to go for it, because finally i want stress, strain rate, strain, material flow as the final  result. 

What do we do?

Yesterday, as I was waiting for the rain to stop before I could walk home from work, a stranger accosted me in the lobby of the building.  He asked me what I did, to which I replied "Mechanics".  He mulled over the answer for a bit and asked me to be more specific, at which point I said that we were trying to design materials that could guide waves around objects.  He said "Water waves?".  I replied "All types of waves."  Clearly, common words can mean quite different things to different people.
