A thin film subject to compressive strain can either bend (for large strain gradient) or wrinkle (for small strain gradient). The bending is traditionally used in thermostats (bimetal stripes), but couple of years ago, it was extended to the nanoscale thin films which can bend and roll-up to tubes with defined number of rotations. The wrinkles are also rather common in macro- and microscale thin films.
Here, we developed an equilibrium phase diagram for the shape of
compressively strained free-hanging films by total strain energy
minimization.

Hi all,

If you can pls advise me to modelthis experiment.

First I have applied a constantload for the steel member.

Then I have increased thetemperature of one of the member surface with time

until the member got failed.

This resulted in non-uniformtemperature variation across the section.

I have measured the temperaturesof the different surfaces of the member and

I would like to use thesetemperature values in my structural modelling.

Now I would like to model themember so that I can find out the time

What are the effects of magnetism on stresses while material is under loading condition?Is there any relationship between magnetism and stress?

Thanks!

Hei,

 I am a new learner of XFEM. I want to start some exmaples in ABAQUS. The tutorial in ABAQUS is rather crude. If any body has experience, May I have small notes on how to solve problems with XFEM in ABAQUS?

Thank you for your help.

Reliability of micro-gears is known to be adversely affected by wear. In this work we report a strategy to predict local wear with the aim of predicting their effective life span. For the prediction of local wear we start from the relevant model experiments, choice of a suitable wear model and identification of the wear coefficient from these experiments. This wear model is then implemented in an efficient finite element based scheme to predict local wear.

Expert programmer needed for an exciting project at the University of Minnesota involving the establishment of an online infrastructure for the evaluation of the transferability of interatomic potentials used in atomistic and multiscale simulations. The project called KIM -- the Knowledgebase of Interatomic Models -- is funded through the NSF's Cyber-Enabled Discovery and Innovation (CDI) program. For more information see the attached PDF file. The position is available immediately.

Sir,

one of my students is working on PhD topic " Study of cold hole expansion and evaluation of fatigue properties on critical aerospace components". His work has to be reviewed by professor of non indian origin in foreign universities. I request you to kindly help this student. If you are interested, let me know, so that I will ask my university to contact you in this regard.

Thanks
