Numerical simulation results(part1): fracture  of multiphase micro flow

explanation:

For the 090*_consise.doc files, down load it and rename it to 090*_consise.avi, then you can open it with winplay

e.g 0903_consie.doc    0903_consise.avi

 

Simualtion of explosion with ABAQUS

Submitted by Wladimir on

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?

Strain compatibility equation in non-linear solid mechanics!!!

Submitted by ramdas chennamsetti on

We have six strain compatibility equations, which are obtained from strain-displacement relations by making an assumptions 'small strains'. Strain compatibility equations ensure a single valued and continuous displacemnet filed. These equations are used in stress based approach.

Now my queries are as following.

[1] Do we have strain compatibility equations for non-linear strain-displacement relations?

[2] Do we follow stress based approach in non-linear solid mechanics.
