A Conforming Augmented Finite Element Method for Modeling Arbitrary Cracking in Solids
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a conforming augmented finite element method (C-AFEM) that can account for arbitrary cracking in solids with similar accuracy of other conforming methods, but with a significantly improved numerical ...
Elastic Metamaterials With Low Frequency Passbands Based on Lattice System With On Site Potential
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An elastic metamaterial with a lowfrequency passband is proposed by imitating a lattice system with linear onsite potential. It is shown that waves can only propagate in the tunable passband. Then, two kinds of elastic ...
