Dear Friends:
As was also mentioned by another colleague (http://imechanica.org/node/20391), Prof. Gérard Maugin passed away on September 22, 2016.
The following is a message that my good friend Prof. Marcelo Epstein sent me and a few other colleagues. He has kindly given me permission to share it with you.

Dear friends,
A finite element software computes the stresses and/or strains sets values at each dynamic iteration step. These values can be plotted on a stress-space giving several failure envelopes. For an isotropic or an homogeneous mixture the Von Mises criterion represents an ideal envelope which may not coincide with the available envelopes but the stresses values can be checked with the material strength.
This paper reports on the experimental assessment of the punching shear behaviour of reinforced recycled concrete slabs characterized by fine natural aggregates and coarse recycled aggregates. In particular, the latter were obtained only from demolished concrete. The experimental campaign has been carried out on 12 specimens. Moreover, three reinforced natural aggregate concrete slabs have been casted and tested as benchmarks. Four replacement percentages (30, 50, 80 and 100%) of coarse recycled aggregates in place of coarse natural aggregates have been considered.
Dear all,
We are easily able to obtain mechanical properties (such as elastic modulus, Poisson's ratio and ...) of a unidirectional lamina composite by means of rule-of-mixture.
For instance, in case of "longitudinal loading", strength of the fiber-reinforced composite for long continuous fibers will be like:
Ec=Ef*Vf+Em*Vm.
I have two main questions:
First, are these relations (longitudinal and transverse loading) hold for bidirectional composite? if not, how can we obtain relative elastic modulus?
The Mechanical Laboratory of Sousse (LMS) of the National School of Engineers of Sousse intends to organize annual scientific workshop on one of the four research themes identified by the laboratory teams. This first Workshop is proposed by the LMS team: “Fatigue of Materials and Structures”. The proposed theme is ” Mechanical performance of materials: From experiments to predictive approaches”.

The Perspective papers published in Journal of Applied Mechanics have attracted a lot of readers, such as the first perspective paper by Huajian Gao (Brown University) which has been downloaded for >8,000 times. A perspective paper, as invited by the editor of JAM, is very short (2~3 pages) and easy to read (like Readers' Digest) to reveal some emerging directions, or some important discoveries in clasical directions, in mechanics.
Join us for the 2016 Composites Simulation Workshop at Purdue University. Learn about and engage with world-class researchers and industry experts in multi-scale composites modeling. Interact with state-of-the-art composites simulation software; hear expert, cutting-edge advances in strength and lifecycle prediction modeling. Experience composites 3D printing and advances in composites manufacturing modeling for high-rate automotive applications.
