Simulation blast in soil by Abaqus
Hello;
H am simulate in ABAQUS a blast in soil.
If in Explicit simulate what is interaction define between TNT & soil?
If simulate by CFD , equation *EOS have not want define.
which way is better?
Thanks.

Mechanics in space (and High School): Lego Man's balloon voyage, or Lego Man in space
For an interesting news article about the mechanics behind Lego Man's balloon voyage to space, read the Toronto Star article by Mary Ormsby. She writes, "A 1,200-gram weather balloon, the crucial role of gravity, quiver-reducing ropes, Styrofoam’s versatility, burst altitude, a University of Wyoming website and a free software program for shutterbugs were part of the formula Mathew Ho and Asad Muhammad, both 17, used to launch, film and land the patriotic, flag-bearing Lego Man..."

Giant, voltage-actuated deformation of a dielectric elastomer under dead load
Far greater voltage-actuated deformation is achievable for a dielectric elastomer under equal-biaxial dead load than under rigid constraint usually employed. Areal strains of 488% are demonstrated. The dead load suppresses electric breakdown, enabling the elastomer to survive the snap-through electromechanical instability. The breakdown voltage is found to increase with the voltage ramp rate. A nonlinear model for viscoelastic dielectric elastomers is developed and shown to be consistent with the experimental observations.

Frictional rolling contact model CONTACT version 12.1 released
Dear all,
Herewith I want to announce the release of the frictional rolling contact model CONTACT version 12.1.
The main changes with respect to earlier versions of the program are as follows:
Postdoctoral Research Associate at Brown University: Finite Element Simulations of Active Biopolymer Networks
A postdoctoral position with
primary focus on finite element simulations of active biopolymer
networks is available immediately at Shenoy Research Group @ Brown University . We are looking for a strongly
motivated candidate to work on the mechanics of active cytoskeletal
networks. The ideal candidate will have a background in solid
mechanics/computational physics with expertise in finite element simulations. Experience with Monte Carlo methods and stochastic simulations is desired but not essential. This
individual will have the opportunity to be directly involved in
UMAT Problem
Hi all,
I am
implementing the constitutive behavior of CuAlNi shape memory alloy during
uniaxial loading using UMAT. My new question is that:
When phase
transformation first starts, umat finds jacobian using my numeric finite
difference method for jacobian. But in same step, stresses and strains cannot
be obtained and then umat uses smaller and different strains and changes
jacobian values. After one step calculation abaqus job finishes with unexpected
error. What could be the problem? What can I do?
Thank you.
