Dear researchers,

Hi all,

I am pleased to post my following publication:

Study on Dynamic Detection of Reinforced Concrete Bridge Damage by Finite Element Model Updating

• Mohammed Lamine Moussaoui ,
• Mohamed Chabaat  ,

Below is a blog post based on equipment that we have built for testing solid ice samples. We designed an ADMET biaxial testing system (eXpert 8600 series) in collaboration with the Rock and Ice Deformation Laboratory (RIDL) at Woods Hole Oceanograhic Institution (WHOI).

Hi All,

My New Scientific Paper is :

Have you ever though about what make composite materials fail under cyclic loading? In the paper we collect evidence of what is fatigue damage actually is. We combine the collected clues into a conceptual model for fatigue damage in unidirectional composites. Next, we formulate a mathematical micromechanical model. The model can predict the fatigue life of a unidirectional fibre composites from the basic mechanics properties of the fibre, matrix and the fibre/matrix interface.

Dear colleagues,

The Frontiers in Robotics and AI has launched a new Research Topic, Soft Robotics based on Liquid Crystal Elastomers (LCEs). 

The submission deadline is 19 January 2022.

Here is the homepage for this research topic:

As a contributing author, you will benefit from:

I bring to your attention this opportunity at the University of L'Aquila.

Kindest regards,

We report phenomenal yield strengths—up to one-fourth of the theoretical strength of silver—recorded in microcompression testing of initially dislocation-free silver micro- and nanocubes synthesized from a multistep seed-growth process. These high strengths and the massive strain bursts that occur upon yield are results of the initially dislocation-free single-crystal structure of the pristine samples that yield through spontaneous nucleation of dislocations.

We introduce a class of parity-time symmetric elastodynamic metamaterials (Ed-MetaMater) whose Hermitian counterpart exhibits unfolding (fractal) spectral symmetries. Our study reveals a scale-free formation of exceptional points in those Ed-MetaMaters whose density is dictated by the fractal dimension of their Hermitian spectra.
