Hello everyone,

I'm working on a linking project between two software: Forge2008 and Abaqus.My goal is to transfert output datas ( nodes,elements, stress tensor) from one software  as input datas for the next one.

In order to realise this task I have to understand the output format .unv of Forge 2008  (Universal I-deas format) and convert this file to .inp ( Abaqus)

And use the subroutine Sigini in Abaqus to put initial conditions.

So to sum up  do you have informations about .unv file (description of elements)

Dear all,

I'm not an expert in using Abaqus. I need an example for modelling delamination with VCCT technique. My model always excited with errors and I dont understand the meaning of them. I posted a blog before, its still that problem. In Abaqus UsersManuel I do not find the right answers. Is it even possible to simulate delamination of a 3d-shell girder with VCCT?

Because VCCT is based on XFEM and I have read somewhere in the Manuel that XFEM is not for 3d-Shell elements. 

Thank you

Kind regards

Hi everybody,I am a senior student in mechanics and I need an example of wave propagation in a thin plate to conduct my project. At now,my main problem is how to model it in Ansys or Abaqus.

Thanks in advance,

We are looking at implementing a non-linear model with friction, and at least in the first place for statics. We haven't found much in the literature on non-linear models for friction in FE.

 Anyone any advice on key papers to read ?

Thanks,

Hi all

I want to do a transient analysis in ANSYS or ABAQUS software.

 but the material has a frequency dependent damping. 

how can I simulate this property in FEM software?

Dear all,

I am considering using OpenSees software in plane strain SSI analysis
under cyclic loading. I have understood, roughly, how the structure of
the input file and the Tcl scripting language work. Nevertheless, I
would like to know; I understand that to model a rigid body, in
OpenSees, you can tie the horizontal and vertical displacements of the
nodes of the rigid entity. Is there any other way? Or did I
misunderstood?

Hi

I have some problems in using  heat effect and temprature gradiant in Sanders shell theory

I will be very appreciated if anyone can help me

thanks a lot 

Hi Every body,

I know that the crack propagation energy release rate G is by defination the release of elastic energy and potential energy of loads per unit area of crack extension and for a linear body loaded by a single load P is given by :

G=P^2/(2b)*dc/da

Any body know if instead of load P, moment M is being used what would be formulation?

I really need this one

Thank you,
