Geometry, topology, and solid mechanics

Differential geometry in simple words is a generalization of calculus on some curved spaces called manifolds. An n-manifold is a space that locally looks like R^n but globally can be very different. The first significant application of differential geometry happened to be in Einstein’s theory of general relativity.

Rapid review and publication at JAM in 2014

Journal of Applied Mechanics (JAM) received 280 submitted manuscripts during the first 6 months in 2014.  Among them only 4 are still in review.  

The average time for the 1st round of review, with the decision to accept, or reject, or revise, is reduced to 10 days.  For those that need revisionsthe average time to make the final decision is 24 days after the 1st round of review, which include both the authors' revision time and 2nd (and more) round(s) of review.

Vibro-acoustics (2 positions)

Noise is one of the vitally important factors determining the quality of life and liveability in urban areas. We have awarded a grant to develop novel windows enabled with green and intelligent sound absorbing materials that have substantially reduced noise transmission, and at the same time maintain ventilation function to realize good thermal comfort and resource efficiency.

new paper on fracking in JAM by Prof. Bazant

Fracking has been an important research topic in recent years.  JAM just published a paper "Why Fracking Works" by Professor Zdenek Bazant and his co-authors (JAM, volume 81, paper 101010, 2014).  This paper is of great interest, not only to mechanics, but also to engineers interested in fracking.

JMPS paper-Micro-buckling in the nanocomposite structure of biological materials

Choose a channel featured in the header of iMechanica: 

Nanocomposite structure, consisting of hard mineral and soft protein, is the elementary building block of biological materials, where the mineral crystals are arranged in a staggered manner in protein matrix. This special alignment of mineral is supposed to be crucial to the structural stability of the biological materials under compressive load, but the underlying mechanism is not yet clear.

Extreme Computing

There have been several discussions on "Extreme Mechanics" in recent weeks and I would like to extend this topic to "Extreme Computing". As we develop materials that are more complex, hierarchical and are spanning multiple spatial scales, we will need computational tools that can describe them well. Fluid dynamics community has long time ago embraced large-scale computing of conservation laws of mass, momentum and energy. In mechanics of materials, large-scale computing is still in infancy.

Recovery of electrical resistance in copper films on PET subjected to a tensile strain

For flexible electronics applications it is important to understand the behavior of electrical resistance of metal films on polymer substrates under applied tensile strain. Although the growth of resistance during tensile loading was investigated in a number of research papers, the recovery of resistance during unloading remains virtually unexplored. In this paper, substantial recovery (decrease) of electrical resistance during and after unloading is demonstrated for copper films on polyethylene terephthalate (PET) substrates subjected to a tensile strain with different peak values.

All -

Are there good references related to acoustic heating?  I am interested in the ability to scale down the effects of this process and looking for ideas in model development to assist.

Fundamental discoveries in mechanics in recent decade or so

A previous post, Getting Ready for Extreme Mechanics Letters, contained the following paragraph:

“We seek papers from researchers in all disciplines. Mechanics appeals to talents of all kinds. Good mechanics has long been created by people from many fields, by Galileo, Newton, Maxwell and Faraday, as well as by Watt, Darwin, Wright brothers and Whitesides. People make discoveries in mechanics often when doing something else (e.g., in seeking evidence for the existence of God, in building cathedrals, in flying airplanes, in laying transatlantic telegraph cables, in fabricating microprocessors, in watching cells move, in fracking for gas, in inventing optical tweezers, in creating soft lithography, in developing wearable or implantable electronics). Mechanics discovered in one field invariably finds applications in other fields.”

Here I would like to give several examples of papers published in recent decade or so. I will link each paper to its citations on Google Scholar, so that you can have an overview of the influence of the paper on other researchers.

Simpleware Case Study: Total Hip Replacement Implant Positioning

CAD and FE models of hip implants

Positioning hip implants poses a number of challenges, particularly in terms of getting bone and implant contact right. While experimental testing can be costly, image-based modelling can be very effective at predicting the best and worst positions for implants. 

Lagrange Multipliers in Multi-body Finite Element Code

Choose a channel featured in the header of iMechanica: 

I'm working on a Multibody dynamics code using the finite element method to simulate the behaviour of flexible beams (using this paper if anyone is interested/ it is relevant). I'd like to model joints, and as I only need spherical friction free joints I believe this should be easy using Lagrange multipliers.
