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.
