How can post buckling analysis be carried out in ANSYS, when element Shell181 is used? what are the various methods and the procedure how to carry out the analysis ???

Can i say, the center of buoyancy and the center of gravity of the immersed part are same?

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

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?
