software

Hello,

I would like to combine Extended Finite Element Method (XFEM) with cohesive behavior in Abaqus to model bulk damage as well as interlaminar damage in a material.

Section 10.6.1 of the Abaqus 6.9 Analysis Users Manual says that XFEM "can be simultaneously used with the surface-based cohesive behavior approach or the Virtual Crack Closure Technique, which are best suited for modeling interfacial delamination."

Does anyone know if XFEM can be combined with element-based cohesive behavior?

Thank you,

Meghan

Hello,

We would like to offer you step by step Video Tutorials of IOSO Optimization coupled with Concepts NREC and NUMECA software:

1) http://vimeo.com/16668245 by this we show how easily you can use direct integration capabilities between IOSO and Concepts NREC software to solve optimization tasks in turbomachinery

2) http://vimeo.com/16805244 here we consider IOSO – NUMECA coupled solution on the example of an optimization case study for turbomachinery

Hi,



I am new to abaqus scripting. I need some help with accessing the odb for history output.



I have a list of odbs and i need to take the displacement and contact stresses information at the end of the step.



The syntax i tried was



import odbAccess





fileName = 'static_open_c1.odb'

stepName = 'Load'

historyRegionName = 'Node HS-1.701'

historyOutputName = 'U2'



session.odbs[fileName].steps[stepName].historyRegions[historyRegionName]

I'm trying to investigate the effect of multiple support excitation (spatially varying ground motion) on seismic response of an arch dam using ADINA, so i need to apply different acceleration (and velocity and displacement) time histories on every node on structure-foundation interface.

Hi all,

I've to model a gearbox in the transitory (acceleration) and in the
stationary (constant speed) running: i'm not sure abut the kind of step
to use.

I'm gonna find contact pressure and stress in both case.



What about using static step for both?

Hi all,

 I need some help with MIMICS software please. I have a CT scan images for the whole body and i need to create 3D object for the shoulder model to each part Humerus and Scapula and then perform some measurments then Export it to ABAQUS. Does any one have any idea. Please help.

My email is: ninaall08 [at] gmail.com

Thank you with my regards

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)
