Hi
I used coupled temperature displacement analysis in Abaqus for simulation hot forming sheet.
obtain negative temperature in coupled temperature displacement analysis in Abaqus.
When I use expansion in analysis below error message is displayed
The Abaqus time increment has become negative?? = -3.60330E-07
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?
Hi
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.

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
I am trying to run user subroutines in fortran, on 64 bit PC. although the verification is ok and all thing is pass, but I got error as:
problem during compilation. I run succesfuly this subrutine with 32 bit pc. the only differences is fortran version in 32 bit 9.1 but in 64 bit 10.1.
any help would be gratefully appreciated.
