I need to model a reinforced concrete beam strengthened externally by frP? Can anyone share useful  material how to model this  in abaqus or ansys ?






svp quelqu'un peut m'aider à installer FRANC2D, et m'indique comment translater un fichier d'ixtension *.inp du abaqus à FRANC2D

et merci d'avence

A FE code with large deformation contact capability and large elasto plastic analysis in Henky strain

Hi every one...

I finished my master in mechanical engineearing about eight month ago ... and in my Master career, I wrote a Fortran Finte element code with capabality of  mortar cantact analysis[1,2] and rate independent plasticity with kinematic and isotropic hardening and with large deformation capabilty for isotropic materials[3,4]. My code converges very well and I achieved quadratic convergence and I didn't use any comercial Fe packages like ansys and abaqus .....

J-integral contour path in ABAQUS

I have calculated the J-integral using ABAQUS for 5 contours but I could not find any information about the paths of the J-integral contours. Do you know how we can get the paths of the requested J-integral contours or equivalently how we can define the paths of contours in ABAQUS? 


element coordinate system orientation after nonlinear static structural solution

Hi. I'm working on multiscale modeling of soft tissues. I'm working
on modeling an orthotropic wavy fiber in WB. I write an APDL routine to
change the element coordinate system of each element with accordance to
the fiber curvature. Ansys documentation said that in the case of large
deflection analysis, the element coordinate system will be rotated with
accordance to element rigid body rotation. My problem is that, after the
solution, the elements coordinate system of some elements rotate

Introduction of the hyperfoam model in ABAQUS

Dear Researchers,


I am trying to find out which was the first ABAQUS version, wchich includes the hyperfoam material model. I haven't found any version history about this. Could someone tell me the very first version of ABAQUS in which the hyperfoam model was included?


Thank You!

Kind Regards,

Attila KOSSA

Modelling of Thermosyphon Evaporator in Abaqus

Is it possible to model and do the thermal analysis of a thermosiphon loop using ABAQUS.

Measure Curved Edge length in ABAQUS CAE

Greetings all,

i want to know, is there any way to measure edge length ( "curves" specifically,  not looking for straight edge length  using distance between vertices as query feature :) ), and also to get vertices co-ordinates in  local co-ordinate system; in ABAQUS CAE or using python scripting.

my problem is somehow related to above query,  can manage solution with 'other' tricks, but want to know any standard methods are avaliable.

Any help is appreciated.



why my umat's behavior degrade in parallel mode?

I've met some strange problems implementing umat. To speak in short, it's parallel degradation, which means when run in serial mode, everything is OK, there's no failure of equilibirium iteration and therefore no cut back, but when switch to parallel mode, there are random cut backs. I checked the process by outputing results to files and found very bizarre phenomenon, the data changes when transfering from the subroutine called to its caller. For example, if the main program calles sub(a), and in sub a is specified intent(out).



I works with subroutins in ABAQUS.

I  have written a vuhard subroutin and I have some problems.

who  does work with this subroutin that can help me?


With regards


Clamping with a specific stiffness in Abaqus

Choose a channel featured in the header of iMechanica: 


is there a simple possibility to set a boundary condition to clamp my sheet in Abaqus with a specific stiffness?

Usually you use the "encastre"-boundary condition. But I would like to give this condition a specific stiffness.

Thanks a lot for your help in advance

which material can be used for modelling a microstucture of metal foams in Abaqus?

I simulate a metal foam microstructure in abaqus but now in material property I dont know which kind of material can I use?

For example I used elasticity and plastic(crushable foam) or elasticity and plastic(isotropic hardening) ?


Why the VVF of GTN model within Abaqus keeps 0

I calculated an example of unaxial tension using GTN model offered by Abaqus. I followed all the instructions found in CAE User's and Analysis User's manual in Abaqus documentation. No error or warning was issued but the result seemed ridiculous, since VVF, VVFG and VVFN keeped 0 throughout the process while equivalent plastic strain keeped increasing(which showed the material had come into plastic deformation). I don't know what went wrong, looking forward to you reply.

Temperature growing Riks step ABAQUS

Hi all

 I am modeling a truss in fire conditions, using ISO 835 fire for it. Now I have included some imperfections on the braces(L/1000) and I would like to know how to run this type of analysis(RIKS)

I used normally two steps, one to define the load on my truss and the second to import the temperatures as a predefined field. At this moment I do not know ho to modify my model steps in order to reach the solution. My temperature analysis takes 30 min and I cannot add time to a riks analysis

Simpleware Case Study: Pseudomorph Modelling

In this project, Simpleware's image processing and mesh generation software was used to complete an ancient geological process through new technology. The goal of the project was to create a pseudomorph, an object that maintains an original shape over time while changing its inner materiality.

rotordynamics analysis by PATRAN and NASTRAN

Hi guys,

    Is there anybody use PATRAN and NASTRAN to simulate rotor-bearing sysytem.

After modeling the shat and meshing it, I don't know which element type can be used to 

analysis the bearing than contain cross stiffness and damping  coefficients.

The following is an exmple:


I can't download the "3DS ACADEMY" tablet application, anyone can?


I have an android 4.3 tablet. but I can't download from this link:

Error message:"This app is incompatible with your device". google not recognize my  android! 

Anyone can download this, and upload for me? or find another link!
