I used coupled temperature displacement analysis in Abaqus for simulation hot forming sheet.

obtain negative temperature in coupled temperature displacement analysis in Abaqus.

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?

negative temperature in coupled temperature displacement analysis in Abaqus

I used coupled temperature displacement analysis in Abaqus for simulation hot forming sheet but obtain negative temperature in coupled temperature displacement analysis in Abaqus.

I think maybe my contact or mesh is not correct.

my step type: Dynamic, Temp-disp, Explicit

mesh type: S4RT

contact type: surface to surface(Explicit) Penalty method contact with termal conductance

Please help me to solve this problem.

Physical significance of strain

Submitted by amitshah3333 on Mon, 04/15/2013 - 11:21

Hi All,

I would like to know about physical significance of Strain. How
it determines failure of structure?

Say for example Compressive strain of concrete being 0.002.
Does it means that if (any) concrete member of original length 100mm deforms 2
mm (when compressed) will fail? Since Strain in this case will be (2/100) =
0.02?

Request you to help me to understand concept of strain.

Thankyou,

Amit
