Hello

brothers

Currently,

I‘m working on the determination of the mechanical properties of carbon nanotubes

for different loading cases using ANSYS software ( i need to use them in my

model). My Finite Element model of graphene and carbon nanotube is working fine with beam188 element, but I have

some technical problems in my simulation. These problem are summarized in

points as follow;

The Mach Conference showcases the state of the art of multiscale research in materials, with an emphasis on advancing the fundamental science and engineering of materials and structures in extreme environments.

Abstracts are due January 6, 2014. For more information, please go to the conference website machconference.org.

a JKR theory of adhesion for anisotropic solids

Submitted by Mike Ciavarella on

Jim Barber and I just got accepted this paper in JMPS, and it is also already available on Arxiv.  We found a remarkably simple closed form solution for adhesion on orthotropic materials in the planes of symmetry.  This shows adhesion can increase significantly due to anisotropy, namely the JKR solution continues to hold in the sense of mean elastic modulus, but the prefactor can grow without limit. We expect applications in crystals indentation, but also in locomotion in biological world.
