Journal Club Theme of January 2012: Mechanics of Growth

"I can't understand how people are still working on growth. That stuff's all done." This was the beginning of the first lunch conversation at a recent Banff workshop on Mathematical Foundations on Mechanical Biology... somewhat frustrating for someone who is excited about growth. Fortunately, most of the presentations and discussions still focused on growth. Although "that stuff's all done".

Would anybody claim that plasticity was all done when Richard von Mises published his milestone work in 1913? Or was it all done when Geoffrey Ingram Taylor contributed his famous monograph on crystal plasticity in 1938? Or was it all done when Ekkehard Kröner introduced the concept of dislocations to explain the mechanistic origin of plastic slip in 1958? Or was it only all done when Juan Simo made it computationally manageable in 1985?

In a way, growth is like plasticity. It has its von Mises in Julius Wolff and D'Arcy Thompson, its Kröners in Steven Cowin and Dennis Carter, and its Simos in Rik Huiskes, Anne Hoger, Larry Taber, and Jay Humphrey. But... does that mean that "that stuff's all done"?

Postdoctoral Research Associate at Brown University: Finite Element Simulations of Active Biopolymer Networks

A postdoctoral position with
primary focus on finite element simulations of active biopolymer
networks is available immediately at Shenoy Research Group @ Brown University . We are looking for a strongly
motivated candidate to work on the mechanics of active cytoskeletal
networks. The ideal candidate will have a background in solid
mechanics/computational physics with expertise in finite element simulations. Experience with Monte Carlo methods and stochastic simulations is desired but not essential.  This
individual will have the opportunity to be directly involved in

A website wholly devoted to buckled shells

John Hutchinson has just pointed out to me the website, shellbuckling.com.  The site is devoted to the mechanics of buckled shells, with downloadable photos, slides, papers, and computer codes.  The site also has a section on buckling people.  The site is created by a veteran buckling person, Dr. David Bushnell, formerly of Lockheed Martin.  Check the site out, and enjoy.

Experimental study on the dielectric properties of polyacrylate dielectric elastomer

The dielectric constant of elastomeric dielectric material is an
essential physical parameter, whose value may affect the
electromechanical deformation of a dielectric elastomer actuator. Since
the dielectric constant is influenced by several external factors as
reported before, and no certain value has been confirmed to our
knowledge, in the present paper, on the basis of systematical comparison
of recent past literature, we conducted extensive works on the
measurement of dielectric properties of VHB films, involving five
influencing factors: prestretch (both equal and unequal biaxial),
electrical frequency, electrode material, stress relaxation time and
temperature. Experimental results directly show that the dielectric

PhD position on tissue engineering of cartilage and mechanical evaluation of the generated tissue

A vacant four-years PhD position is available. This PhD project will be done in Erasmus Medical Center (Rotterdam, NL) in collaboration with Delft University of Technology (Delft, NL) and is a part of a larger Dutch project on regenerative medicine and tissue engineering. The aim of the project is to generate cartilage from bone marrow derived stem cells in culture and evaluate them with molecular assays (Rotterdam) and mechanical assays (Delft). The culture protocol can be varied with oxygen level, tonicity, and active molecules.

Hyperelastic material characterization: why they call it the pure shear specimen

Many people puzzle over the nomenclature of the pure shear test. They rightly point out that 1) the Pure Shear test piece is loaded in tension by extending the specimen in the axial direction, and 2) a shearing deformation, by definition, involves the lateral motion of parallel planes. They wonder where is the "shear"? and what does it mean to say that the shear is "pure"?  Here, we review the origins of the terminology.
