Abaqus Quasi-static induced numerical damping

The Quasi-static method for dynamic problem in Abaqus should be carefully used, because it will automatically induce the numerical damping in your calculation.

This method is very conservative, approximately it will introduce 5% numerical damping (damping ratio).

This method is helpful for contact problem and for convergency. But be careful when using it.

FEAP - history variables for Elements

Submitted by Mubeen on

Hi all,

my question is about the history data storage in FEAP.

I am writing element subroutine (elmt01) in FEAP 8.3  for a history dependent problem.

I have written the stiffness matrix subroutine (stiff01), but it needs the data from the previous solution steps (previous strains, stresses, plastic strains, dislocation densities .... nh1,nh2=30 per point).

Scanning Valves Efficiently And Precisely Is Often A Nightmare

PROFILOMETER

Traditional ways of valve inspection using a contact profilometer are making way for the more recent non contact valve inspection technologies. Even though many of the specs of surface roughness globally are set as per the findings by a contact profilometer the ease of non-contact inspection systems plus the speedier technique of employing the high tech valve inspection technologies are definitely behind why significantly more professionals are purchasing the newest non-contact profilometer.

Great things about a customized valve inspection set-up

International Conference on Computational Mechanics, Durham, UK, 25-27 March 2013

Submitted by Charles Augarde on

Dear Colleagues, On behalf of the CM13 Organising Committee, I would like to invite you to attend an International Conference on Computational Mechanics - CM13, to be held in Durham, UK from 25-27 March 2013. The conference is organised under the banner of the UK Association of Computational Mechanics in Engineering (ACME) replacing, for 2013, the annual ACME meeting with a much larger and truly international event. A flyer containing full details of the conference can be downloaded here.

Abaqus/Explicit memory usage

Submitted by Bunnu mobile on



Hi all. I am running forming analysis on abaqus 6.10 on 64 bit platform with 8 gb of RAM. How can I give max memory usage for abaqus/explicit? There is a built in option for abaqus/implicit but for explicit there is no such option.



I want to allocate max amount of RAM for the analysis. Please help me with that.
