Journal ArticleDOI
Peridynamic States and Constitutive Modeling
TL;DR: In this article, a generalization of the original peridynamic framework for solid mechanics is proposed, which allows the response of a material at a point to depend collectively on the deformation of all bonds connected to the point.
Journal ArticleDOI
Convergence, adaptive refinement, and scaling in 1D peridynamics
Florin Bobaru,Mijia Yang,Mijia Yang,Leonardo Frota Alves,Stewart A. Silling,Ebrahim Askari,Jifeng Xu +6 more
TL;DR: In this paper, adaptive refinement algorithms for non-local method peridynamics were introduced for scaling of the micromodulus and horizon and discussed the particular features of adaptivity for which multiscale modeling and grid refinement are closely connected.
Journal ArticleDOI
A non-ordinary state-based peridynamic method to model solid material deformation and fracture
TL;DR: In this paper, a non-ordinary state-based peridynamic method was developed to solve transient dynamic solid mechanics problems, in which the bonds are not restricted to central forces, nor is it restricted to a Poisson's ratio of 1/4 as with the bond-based method.
Journal ArticleDOI
Peridynamic Analysis of Impact Damage in Composite Laminates
TL;DR: The peridynamic model of solid mechanics has been developed for applications involving discontinuities as mentioned in this paper, which treats crack and fracture as just another type of deformation, rather than as pathology that requires special mathematical treatment.
