2-D "tension-shear chain" model (Ref.1-3) is well known successfully capturing the basic mechanical features of staggered structures in shell-like biomaterials. Our recent paper appeared in Comp. Sci. Tech. developed a three-dimensional (3D) "tension-shear chain" theoretical model to predict the mechanical properties of unidirectional short fiber reinforced composites, and especially to investigate the distribution effect of short fibers.

Hello,

I want your help

I'm doing a model by ABAQUS. I want to apply force in the first step and after that I want to change the geometry in the second step (I want to do a hole in my geometry).

How can I change my geometry after applying the force?

can you help me please?

Thanks

I am cuurently using 12 ply GFRP. After submtting the job file, the visualisation of the displacement showed ther is non-contact between the ply at free end. I ma uusing a model of free baem cantilever.

How to ensure there is no such non contact between the plies?

Hi all,

I am a PhD researcher working on relationship between cracking of concrete and its durability, using both experimental and numerical approaches. The work is being carried out at Delft University of Technology, in the Netherlands. For anyone interested, here is the webpage of the project:

What makes glass brittle? I am posting this because I don't have a good answer for it, although I can think of three reasons:

-
The disordered structure of glass.  The problem with this explanation
is that silica is brittle in both ordered (quartz) and disordered (fused
silica) forms.

-
The covalent type of atomic bonds. The problem with this explanation is
that metallic glasses do not have covalent bonds, but are brittle.

Hi, i need code c++ or matlab FMBEM 3D .anyone can help me?

thanks.

Anybody working on fringe analysis using ESPI (Electronic Speckle Pattern Interferometry)?

I want to study post doc, my beckground is;  

concluded my doctoral thesis, in 2010, on “Design Of A Composite Tube Under
High Temprature And Dynamic Pressure Loading” at Kırıkkale University, Turkey.
Previously, I gratuaded from Istanbul Technical University and Gazi University
with honoured degree. I also studied on fracture mechanics, fatique
characteristics of mechanics and compututional mechanics with finite element
methods.

I need to write a Vumat subroutine in ABAQUS 6.11.1, and I dont know where should I begin from exactly? can anybody help me with the suitable version of Fortran for this version of ABAQUS and the steps I need to take for writing a SUBROUTINE in ABAQUS?

 Thank you guys
