Dear Friends,
You may like to read one of my articles which recently got accepted in the Journal of Elasticity. It is titled "A helical Cauchy-Born rule for special Cosserat rod modeling of nano and continuum rods". The Cauchy-Born rule was primarily introduced for constitutive modeling of bulk crystals as three-dimensional elastic bodies. Arroyo & Belytschko later proposed exponential CB rule for shell-like nanostructures. Here, we have proposed a novel "helical Cauchy-Born rule" to derive nonlinear constitutive laws of rod-like nanostructures from atomic level computations.
The article is now available at the folliwng link: http://link.springer.com/article/10.1007%2Fs10659-015-9562-1
