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.
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.

A postdoctoral researcher position is open in the Integrated Design Automation Laboratoryjointly with the Advanced Materials Laboratory at Northwestern University under the guidance of Prof. Wei Chen and Prof.

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
Dear Colleagues:
The 14th U.S. National Congress on Computational Mechanics (USNCCM14) will be held at the Palais des Congrès de Montréal, QC, Canada, July 17-20, 2017 (http://14.usnccm.org/).
As a part of this meeting, we are organizing a mini-symposium to address recent advances in Modeling Materials with Coupled Physics (http://14.usnccm.org/MS709). Topics of particular interest include (but not limited to)
For the first time, a design of a “deflecting elastic prism” is proposed and implemented for waves in a chiral medium. A novel model of an elastic lattice connected to a non-uniform system of gyroscopic spinners is designed to create a unidirectional wave pattern, which can be diverted by modifying the arrangement of the spinners within the medium.
Spend a week at MIT and earn a MIT certificate. A great opportunity for postdocs and graduate students. Limited number of fellowships available.
June 12-16, 2017
