How to include water buoyancies effect in analysis for an abaqus model. The abaqus model is developed using shell and solid elements

An exciting new research position for a Postdoctoral Research Associate is
now available in a project funded by the Australian Research Council, led by Professor Itai
Einav and Dr Luming
Shen. The project is to study fragmentation waves in granular materials,
applicable in geosciences, and in engineering problems of material mining,
petroleum processes, and pharmaceutical operations.

Shannon-type expected information gain can be used to evaluate the
relevance of a proposed experiment subjected to uncertainty. The
estimation of such gain, however, relies on a double-loop integration.
Moreover, its numerical integration in multi-dimensional cases, e.g.,
when using Monte Carlo sampling methods, is therefore computationally
too expensive for realistic physical models, especially for those
involving the solution of partial differential equations. In this work,
we present a new methodology, based on the Laplace approximation for the
integration of the posterior probability density function (pdf), to
accelerate the estimation of the expected information gains in the model
parameters and predictive quantities of interest. We obtain a

I've modelled a DCB specimen and applied Boundary conditions and load... I followed the same procedures given in abaqus documentation... As expected the crack initiates and propagates along the interface... I can get the Resultant force vs displacement plot from the analysis.. But i dont know how to plot the fracture toughness vs crack length plot in ABAQUS..

Please help me... Your suggestion would really help me a lot..

A simple 3D D3Q27 lattice Boltzmann example for simulate the plastic creep simulation on the friction surface 

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,

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.

Dear Gropu member,

 I am josyula, working on machinability study of composites on abaqus .

1) i need help in modeling of particulate reinforce composite.

2) i need help in simulation of turning  in abaqus.

 if an body know anything about modeling and simulation reply me  or guide me properly to achive  out put.

 thank

Dear Friends,

Hi! all

I have conducted several test of steel plate under cyclic load in order to get hysteretic cuve. some specimens showed a significant differences between tension and compression load. I read from texbook about this phenomena and it say because of bauschinger effect. Iam wondering why the diffrences to large and sometimes more than 50%. I am very appreciate if some one can explain about this problem.

regards

danile
