Discrete dynamical stabilization of a naturally diverging mass in a harmonically time-varying potential
Arnaud Lazarus
We numerically investigate the stability and linear oscillatory behavior of a naturally diverging mass whose potential energy is harmonically modulated. It is known that in the Kap…
Micromechanics based framework with second-order damage tensors
Rodrigue Desmorat, Boris Desmorat, Marc Olive +1
The harmonic product of tensors---leading to the concept of harmonic factorization---has been defined in a previous work (Olive et al, 2017). In the practical case of 3D crack dens…
Buckling of an elastic ridge: competition between wrinkles and creases
Claire Lestringant, Corrado Maurini, Arnaud Lazarus +1
We investigate the elastic buckling of a triangular prism made of a soft elastomer. A face of the prism is bonded to a stiff slab that imposes an average axial compression. We obse…
Coda reconstruction from cross-correlation of a diffuse field on thin elastic plates
Aida Hejazi Nooghabi, Lapo Boschi, Philippe Roux +1
This study contributes to the evaluation of the robustness and accuracy of Green's function reconstruction from cross-correlation of strongly dispersed reverberated signals, with d…
