Hi

 

Sorry in advance, but this will be a long story...
Thank you for taking the time to look at it! :)

 

I have a 2D model that worked fine until a couple of
days ago where I tried changing the mesh a bit. Now when I try to run it aborts
calculation and gives some of the following errors:

 

- There are 14 unconnected regions in the model.

Extract natural frequencies in abaqus

Hi all,

 I am new in the blog, so I would like to appologies if this post is already published.

 I am doing a research in vibracion-based health monitoring based in CFRP beams. As a part of my research, I am modeling a composite beam in abaqus and apply transient analysis on it. Before I would like to validate my model with a very simple a easy model for this reason I have elaborated this procedure:

Beam-Shell contact in Abaqus

Hello everybody.

 

I am doing my diploma project and I have to model an off-shore oil-rig in Abaqus. It's a metallic truss-type system. I've defined all of the elements composing the structure as wire elements and the decks as solids. Does anybody know how to define the contact between the decks and the supporting beams? The decks are supposed to be bolted to the beams.

 

 

Simulation of composite delamination caused by impact

Submitted by zhang922 on

Hi All,

While using LS-DYNA to simulate the impact damage of composites, I have a question about modeling.

I plan to create the model by solid element. Each ply has one element in the thickness direction. The contact between plies is *contact_automatic_surface_to_surface_tiebreak. My question is how to create separate ply models while using this contact. It is clear that common nodes are not allowed. So there might be two possibilities.

Simulation of solids mechanics with impact contact and friction, The Siconos software release 3.5.0

Submitted by vacary on

Dear colleagues,

For people interesting in the simulation of solids mechanics with impact contact and friction, we are pleased to announce the release 3.5.0 of the Siconos software. The software is open-source, under GPL Licence and can be found at http://siconos.gforge.inria.fr/

It contains several time--stepping integrators for the nonsmooth dynamics and a large colection of solvers of the frictional contact problems that can be used separately.
