LIVE WEBINAR - Realtime Design & Engineering Reviews
We would like to invite you to join our third webinar
When:
ASM Educational Symposium: Innovations in Mechanical Testing: From Molecules to Large Engineering Structures
Dear iMechanica Readers,
Greetings from Oak Ridge.
I would like to invite you, your colleagues and students to attend the annual Educational Symposium organized by the Oak Ridge Chapter of ASM International. The theme for this year’s symposium is:
“Innovations in Mechanical Testing: From Molecules to Large Engineering Structures”
We have an outstanding list of speakers, which includes:
Ian Robertson (NSF) - "In situ TEM testing" (Keynote Speaker)
FEM simulations of indentation test
Hello Everybody,
Does anybody have experience with simulations of indentation in axysymmetrical case, it seems that adaptive meshing doesn't work in ABAQUS Standard.
Best regards

Ansys File Import
I am working on a FEM project in which i should import a complicated 3D model to Ansys.
I created The IGES format of the model which the size was 52Mb for the IGES file.The model contains very curvy surfaces and it is complicated.it is created By 3D doctor....
when i import it to ANSYS it doesnt create any volume and i can see only small areas.
now how can i make the model more handy for ansys....also i need to have a volume in order to meshing....
could u please help me to get out through this?
Thanks
Computing Thermal Stresses for Composite using ABAQUS/CAE
Hi,
I am new in ABAQUS. I am trying to find the thermal stresses created by change in temparature of 50'C for lainate consisting of [90/+45/-45/0]s configuration. Eventually what I intend to do is find the stresses under a simple uniaxial load which also consider the change of temperature while calculating the stresses in each ply. I have the material data for the coefficinet of thermal expansion both for longitudinal and trnasverse directions (alpha_11 and alpha_22).
Is there any suggetion of approches I may take.
Many thanks in advane !!!!
ANSYS error
Hi everyone
A NASA paper demand
Hi everyone
I need a NASA article and I have few information about how to get access to it. Here is its title and hyperlink.

longitudinal compression and shear: Results obtained with PASCO,
EAL, and STAGS computer programs,TROUD, W J | GREENE, W H | ANDERSON, M S"
modelling weld joint in ansys
anybody please help me to model the weld joint in ansys.or Are there any such tutorial to model such joints?
high strain rate in MD simulations
Dear All,
Recently I have read some literatures on Molecular simulation of polymer. My interest is measurement of
mechanical properties of polymer through the uniaxial tensile test.
I have a question about relatively large time scales in MD simulations of polymer and how to interpret MD
stress-strain results for FE modeling. In particular, in the literature it is mentioned that strain rate of
Incompatibility between UMAT and varied versions of Abaqus
Hi everyone,
I encountered a problem while runing a UMAT in Abaqus 6.9, which
kept aborting with a systme error code 693. The UMAT is wriiten in
Abaqus 6.5 and prove runing well in 6.5. But when putting it in 6.9, it
always failed. I can not figure out what going on there. Do you have
good ideas?
The error message is like
The system erro code 693
