PhD position in Prof. Nadimpalli's group at NJIT

Submitted by Siva P V Nadimpalli on

Hello All,

There is a potential opening for a PhD student in Prof. Nadimpalli’s group at the New Jersey Institute of Technology starting from Fall2017. Candidates with good academic credentials and an interest to work in experimental research projects are encouraged to apply. Ideal candidate should have a master’s degree in mechanical/materials science/aerospace or related field with a good background in Solid Mechanics, Materials Science, and Experimental Methods (including but not limited to SEM, TEM, and nanofabrication methods).

The Workshop is funded by the European Commission Enlargement Programme. There is no fee to attend.  Participants from the target countries* can apply for a Grant to cover their cost.  Eligible for Grants are those that work in or are citizens of a target country.

The Workshop will consist of invited keynote presentations, oral presentations by participants and a Poster session.

Soft Materials Mechanics and the 2017 ASME IMECE

Submitted by mechanics.soft… on

Dear Colleagues,

The Soft Materials Mechanics Technical Committee (TC) is pleased to announce that the abstract submission process for the 2017 ASME IMECE in Tampa, FL is open. The TC symposium solicits abstracts from many disciplines represented from previous years (active materials, gels, biomaterials, 3D printing, and more) as well new subject areas and collaborations.

Issues with implementation of strain gradient plasticity framework of Niordson and Hutchinson (2003) in Abaqus UEL subroutine

Submitted by Suman.Guha on

I have implemented the rate-independent strain gradient plasticity framework of Niordson and Hutchinson (2003) in UEL. I was able to validate the results of the shear of infinitely wide thin layer between two rigid surfaces (Niordson and Hutchinson, 2003). However, the UEL subroutine fails to converge for the more complex problem of the shear of finite width slab. I suspect the convergence issues are arising out of internal elastic-plastic boundary conditions and the yield criteria. I have few doubts in this regard.

Is there any dissymetry of lift in the forward flight of the helicopter after applying the cyclic control?

Submitted by seepratik on

Dear friends,

I was curious about the time varying loads on the helicopter blades in the forward flight. After reaching lots of books and documents, I came to know that some control (cyclic) is applied to take care of the dissymetry of lift in the forward flight. My question is, if the dissymetry of lift is eliminated by applying the cyclic control or by blade flapping (whatever), then why the load should vary with time for the 90 and 270 position of the blade? Can anybody explain this? Please let me know the justification. I am really curious about it. 

Thanks
