Load‑bearing behaviors of sandwich plates with non‑uniformly distributed grid cores : Static compression and bending by Hao, Ning, Wang, Youlong, Song, Yiheng, Ruan, Sihan, Quanjin, Ma, Wang, Ziying

“…Under bending loading, most NUGPs experience local failure at the loading head, while the specific category surpassing GPs undergoes shear buckling in longer grid walls. (3) Deformation modes of the core layer, mechanical analysis, thin plate buckling theory, and equivalent bending stiffness calculations elucidate the load-bearing mechanisms of NUGPs. These findings enhance topology optimization research for sandwich plates, provide guidance for grid wall arrangements under different loading conditions, and offer insights for designing lightweight sandwich structures.…”

Microscopic dynamics underlying the stress relaxation of arrested soft materials by Song, Jake, Zhang, Qingteng, de Quesada, Felipe, Rizvi, Mehedi H., Tracy, Joseph B., Ilavsky, Jan, Narayanan, Suresh, Del Gado, Emanuela, Leheny, Robert L., Holten-Andersen, Niels, McKinley, Gareth H.

“…We also show that perturbing the system via small mechanical deformations can result in large intermittent fluctuations in the form of avalanches, which give rise to a broad non-Gaussian spectrum of relaxation modes at short times that is observed in stress relaxation measurements. These findings suggest that the linear viscoelastic stress relaxation in arrested soft materials may be governed by nonlinear phenomena involving an interplay of internal stress relaxations and perturbation-induced intermittent avalanches.…”
