Postdoc Position in Computational Mechanics - Ohio State University

The Automated Computational Mechanics Laboratory (ACML) at The Ohio State University has an immediate opening for a one-year postdoctoral research associate position. The project is aimed at the application of the finite element method for simulating and optimizing the laser ablation process in aircrafts. The optimization process involves characterizing the optimal laser parameters (e.g., peak power, fluence, intensity, etc.) to maximize the coating removal efficiency while minimizing damage to the substrate material.

Update: Journal Club Entry July 2014: Overcoming Challenges in Liquid Crystalline Elastomers

Dear iMechanica,

Last July I posted a journal club entry on overcoming the traditional challenges in mechanically actuating liquid-crystalline elastomers ( I'm glad to say we finally got our first manuscript regarding this work published in RSC Advances (DOI: 10.1039/C5RA01039J). 

Model for static and kinetic friction (rate and state)

We recently proposed a model for rate and state friction by studying the collective (statistical) behavior of viscoelastic asperities. Various observed features of friction emerge as collective phenomena, without postulating them directly at the microscale. The paper is available at the link below.


Thank you.

How to determine elastic constants of transversely isotropic material by tension experiment?

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. Stated simply, given the fact that local strain rates in a notch are significantly higher than in the rest of the bar, the notch will harden to an extent that it transfers the load elsewhere in the specimen.

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.
