Journal ArticleDOI
A meshfree method based on the peridynamic model of solid mechanics
TL;DR: In this article, a numerical method for solving dynamic problems within the peridynamic theory is described, and the properties of the method for modeling brittle dynamic crack growth are discussed, as well as its accuracy and numerical stability.
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
Peridynamics for multiscale materials modeling
Ebrahim Askari,Florin Bobaru,Richard B. Lehoucq,Michael L. Parks,Stewart A. Silling,Olaf Weckner +5 more
TL;DR: Peridynamics as discussed by the authors is a continuum theory that employs a nonlocal model of force interaction, where the stress/strain relationship of classical elasticity is replaced by an integral operator that sums internal forces separated by a finite distance.
Journal ArticleDOI
Crack nucleation in a peridynamic solid
TL;DR: In this paper, a condition for the emergence of a discontinuity in an elastic peridynamic body is pro- posed, resulting in a material stability condition for crack nucleation.
