Element differential method for free and forced vibration analysis for solids
Jun Lv,Chang Song,Xiao-Wei Gao +2 more
TL;DR: A new strong-form numerical method, element differential method (EDM), is proposed to perform free and forced vibration analysis of elastodynamic problems and establishes the global algebraic system equations directly based on the strong form of the equilibrium equations without using any variational principles or energy principles.
Journal ArticleDOI
Two-Scale Topology Optimization of the 3D Plant-Inspired Adaptive Cellular Structures for Morphing Applications
TL;DR: A novel two-scale topology optimization method is developed to optimize three-dimensional (3D) plant-inspired fluidic adaptive cellular structures for morphing applications.
Journal ArticleDOI
Geometrically nonlinear analysis of 3D fluid actuated cellular structures using extended multiscale finite element method
TL;DR: The results demonstrated that the developed nonlinear multiscale formulation for the 3D problems could provide high precision solutions as well as acceptable numerical efficiencies.
Journal ArticleDOI
Extended multiscale finite element method based on polyhedral coarse grid elements for heterogeneous materials and structures
TL;DR: In this paper, a three-dimensional multiscale approach based on the theoretical framework of the multi-scale finite element method is proposed to solve the behaviors of heterogeneous materials and structures containing irregular polyhedral inclusions with arbitrary numbers of vertices and faces.
