Rib-Reinforced Ultralight and Ultra-Strong Shell Lattices. [PDF]
Adv Sci (Weinh)This study thoroughly reveals the relation between the curvature and stress direction of triply periodic minimal surface (TPMS) thin shell lattices and proposes a novel rib reinforcement design strategy to incorporate ribs along the line of asymptotes (LOA) and the line of principal curvatures (LOC) to enhance the strength of ultralight TPMS shell ...

Imperfection-Enabled Strengthening of Ultra-Lightweight Lattice Materials. [PDF]
Adv Sci (Weinh)This study identifies different compressive failure modes of cubic lattices with different relative densities and proposes a novel imperfection‐enabled strengthening mechanism of ultra‐lightweight lattice materials. Geometric imperfections are proven to be advantageous in enhancing the stability and strength of lattice materials at ultra‐low relative ...

Asymptotic analysis of plates in static and dynamic strain gradient elasticity
Comptes Rendus. Mécanique, 2022 We study the steady-state and transient responses of a second-order elastic plate by implementing an asymptotic analysis of the three-dimensional equations with respect to two geometric characteristics seen as parameters: the thickness of the plate and ...

Meshless Modelling of Laminate Mindlin Plates under Dynamic Loads
Communications, 2012 Collocation method and Galerkin method have been dominant in the existing meshless methods. A meshless local Petrov-Galerkin (MLPG) method is applied to solve laminate plate problems described by the Reissner-Mindlin theory for transient dynamic loads ...
