[GiDlist] RV: contact element

Post by Nubia Aurora Gonzalez »

Dear Emad,

Recently, a coupled THM Joint element with double nodes has been
implemented in Code_Bright (CB) using the option of contact surface of
GiD (Geometry/Create/Contact surface), in this element, there is a
one-to-one relationship between the nodes of the master and slave parts.

Once the contact surface is created, a special material (with mechanical
and hydraulic data for the joint element) has to be assigned to the
surface. The mechanical behaviour of the joint is described using a
constitutive law for pre-existing discontinuities, this can be elastic
or visco-plastic. The diffusion model considers advective and
non-advective fluxes along the joint elements. There is also the
possibility that the joint be or could become, unsaturated. You can find
more information in the manual (CB_PartVIa and CB_PartVIb) that can be
download from the web site
(https://www.etcg.upc.edu/recerca/webs/code_bright/v3/), as well as the
latest version of CB.

We are preparing some tutorials to illustrate the use of the joint
elements, so, I will inform to you when them can be available.

Please, do not hesitate in write me, if you need more details or you
have questions.

Best regards,

Buenas Nubia,

No sé si tu eres la persona indicada, pero te reenvio una consulta que nos hace un usuario de CodeBright (mail de más abajo).

Hasta luego,

ABEL

I am not a Code_Bright user,
ask its developers to know if this program support contacts http://www.etcg.upc.edu/recerca/webs/code_bright/v3?set_language=ca
and how must be defined in the interface from the user point of view.

Regards

Enrique

Thanks Dear Enrique,

The analysis code that I use is Code_Bright and I don’t know which kind of
relationship exists between the nodes of the master and slave parts. Do
you have more information about the contact analysis in this code?
Best regards

Dear Emad,

What is the analysis code that you will use to calculate this
soil-structure
case?
How are 'contact elements' for this code?
e.g.
a) some solvers requiere to define a master and a slave surface mesh,
but
the elements of both surfaces are not 'one-to-one' related
b) other programs require a one-to-one relationship between the nodes
of the
master and slave parts, and a link between them to know how are
related.

If your program is of type a) the usual way is to define in the
problemtype
a GiD condition to handle this information, and mark parts as master
and
slave, and the simulation data (like shear parameters)

If your program is of type b) you need to force this special
one-to-one
mesh, then you can use the 'special pseudo-geometric entity: contact'
(menu:
Geomtry-Create-Contact)
(contact volume for 3D cases). Two master-slave 'equal surfaces' must
be
selected, and a kind of semi-structured mesh will be created, having
one-to-one nodes.
The shear parameters could be assigned to this 'special contact
volume' with
an additional condition aplied over these volumes.

Hello everybody,

I use GID 10 to simulate soil-structure interaction for pile
foundations.
I would like to know if is possible to add a contact element in
order to
consider the soil-pile interface behavior (e.x with shear
parameters).

Thank you
Emad
