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.

Analytical solution for deflection of plate

Submitted by J. K. Phadikar on

I am a third yr undergraduate student of Aerospace Engineering department, IIT Kharagpur. I have a very simple question in strucutral mechanics. Is there any analytical solution available for deflection of plate under distributed load? The governing equation is well known and has been attached as an image file. Only classical plate theory can be considered. The boundary conditions can be taken as classical boundary conditions. So that can be any combination of a) hinged b) clamped and c) free boundary conditions.
