Dear Mechanician,
A novel method for the identification of higher-order continua equivalent to a Cauchy composite has been published, as a result of the collaboration between the following two ERC projects:

Abstract:
A PhD scholarship is available at PIMM laboratory to work on the topology optimization of lattice structures obtained by additive manufacturing.
See the file attached for description.
Applications are sought for one Post-Doctoral Researcher at University of California, San Diego (USA) to join the M2DO research lab. The primary research focus is to develop topology optimization for multiscale and multiphysics problems optimizing materials and structures.
Relevant research background in the following areas are encouraged to apply:
I found this reference very helpful in building a solid base for learning the foundamentals of Homogenization methods and up to now, is the only reference that addresses the difference between Homogenization and Averaging methods.
I will put more references in this entry and will be happy if you share your links with me.

We've recently published an open access journal paper that looks at the mechanics of sutures used to repair severed tendons. A homogenization strategy is used to derive effective elastic properties for tendon fibrils and intracellular matrix. We have found that regions of high stress correlate with the regions of cell death (necrosis) that are sometimes observed in patients.
If this is of interest, please feel free to view the paper here.
This paper presents a homogenization-based constitutive model for the mechanical behavior of particle-reinforced elastomers with random microstructures subjected to finite deformations. The model is based on a recently developed homogenization method (Avazmohammadi and Ponte Castaneda 2013; J. Elasticity 112, 1828–1850) for two-phase, hyperelastic composites, and is able to directly account for the shape, orientation, and concentration of the particles.
Hello,
I read that "In general, even if the materials on the micro-level are isotropic, the effective
material can show anisotropic behavior. A general anisotropic linear elastic material
may have twenty one independent material parameters.''
If I understand my results correctly then simple structures like ''ball in the unit cell'' result in orthotropic material.
I am a bit puzzled - what would be the simplest structure that would result in anisotropic material behaviour?
This is a reminder to invite you to submit an abstract for the 24th International Workshop on
Computational Mechanics of Materials (IWCMM 24) in Madrid, Spain on October 1st-3rd.
The abstract submission will close in
less than 3 weeks.
In 2012 and 2013 we organized very successful Workshops on
"Physics-based material models and experimental observations" funded
by the European Union's Enlargement programme. We cordially invite you to
submit an abstract to the 3rd International Workshop on Physics Based
Material Models and Experimental Observations to be held on 2-4 June
2014 in Cesme-Izmir/Turkey.
