Biographical Memoir of Zay Jeffries by W.D. Nix

Submitted by William D. Nix on Tue, 05/14/2013 - 04:33

I have written a National Academy of Sciences biographical memoir of Zay Jeffries, one of the great American metallurgists of the 20th century. I am posting the link to the NAS website here with the thought that some readers of iMechanica might be interested in the piece. Some will be interested to learn that Jeffries came very close to discovering dislocations some 18 years before the great papers of Taylor, Orowan and Polyanyi in 1934.

Johsnon-cook model

Hello All!!!

I am Arun, Master degree student in South Korea.

My research field is : High strain rate experiemnts

I did High speed tensile test for aluminium alloy at four different speeds (1m/s, 5m/s, 10m/s and 15m/s)

I also did high temp tensile test for aluminium alloy at room temperature, 100 C, 250C

Now i have the stress Vs Strain curve for High speed tensile test and high temperature test

But, i don't know how to determine Johnson-Cook model parameter from the experimental results

TNT expolosion

I'm trying to simulate with ABAQUS a explosion of TNT and the effect of that on a metal panel. The metal panel is 200mm away from explosive. It is about 100g TNT. I now about the subroutine VDLOAD. Which options I could use else in ABAQUS? Is it posible to define a explosion lake this with *EOS? If yes, which element type I should use for explosive set? Should I define a element set for air, if I use *EOS?
