Summit on Predictive Modeling of Ductile Failure
Place: AT&T Executive Education and Conference Center, University of Texas at Austin, Austin, TX
Dates: March 2-3, 2015
Position Open at NUS (Singapore): Research Fellow
One Research Fellow (Post-doc) position is open at the National University of Singapore.
If hired, you will work at Soft Materials Lab @ Advanced Robotics Centre (ARC), which I head.
Job Desription: Conduct research on biomechanics of the human motion, and how to effectively harvest energy from these motions using a soft and stretchable generator. You are expected to perform both theoretical and experimental investigation, produce research papers and perhaps, file patents.

How to determine elastic constants of transversely isotropic material by tension experiment?
Forums
Hello. I am working to design an experiment to determine elastic constants of transversely isotropic material (also plastic-like material). There are five independent coefficients, and with experiment methods described in this paper doi:10.1016/j.ijrmms.2011.12.004, I need to carry out at least 3 tensile experiments. In the experiments, I need to measure not only the tensile strain-stress curve, but also at least one transverse strain to determine the poisson's ratio in the plane of transverse isotropy to a stress acting parallelly to it.

Dynamic necking can avoid notches
Following an earlier post on dynamic necking of tensile bars, we show in the attached paper (to appear in JMPS) that the presence of deep notches in the specimen does not necessarily dictate the location of the neck. Various material parameters are identified and modeled numerically, to assess their respective influence. Strain-rate sensitivity is identified as an important factor.
Surface preparation of dental implants
It is commonly admitted that "rough" surfaces promote osseo-integration of dental implants. Numerous studies emphasize an optimal Ra parameter for this purpose. One very common way to achieve that state is the so-called "grit blasting" process whereby tiny ceramic (alumina) particles are shot on the implant's surface.
Up to here for the basic story.
It has also been noted in other instances that surface blasting may not be entirely beneficial and it should be controlled, in terms of blasting pressure, particle size and shape.
