postdoctoral position
The research group of Structural Composites at IMDEA Materials (Madrid, Spain), led by Dr. Cláudio S. Lopes and Dr. Carlos González, invites applications for a Postdoctoral Fellow in the field of multiscale computational analysis of composite structures. Candidates with strong background knowledge on computational damage mechanics, model development, and on numerical simulation of advanced composite materials and structures are strongly encouraged to apply. Experience in experimental mechanical testing of composites is highly valued.
 

relation between the Euler-Lagrange strain tensor and the 2nd Piola-Kirchhoff stress tensor

Submitted by xalbert76 on
research

At finite deformations, the 2nd Piola-Kirchhoff stress tensor S_{IJ} is work-conjugate to the Euler-Lagrange strain tensor E_{IJ}, i.e. the work done by the stress S_{IJ} at developing a strain E_{IJ} per unit volume in the reference configuration is

W = 1/2 S_{IJ} E_{IJ}  (Einstein summation over repeated indices implied)

I would like to express this in the same form as used in linear elasticity, i.e. to write S_{IJ} = M_{IJKL} E_{KL}, which would give me

W = 1/2 M_{IJKL} E_{IJ} E_{KL}

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;

a JKR theory of adhesion for anisotropic solids

Submitted by Mike Ciavarella on
adhesion
anisotropic elasticity
JKR

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.
