Journal ArticleDOI
Inelastic peridynamic model for molecular crystal particles
Stewart A. Silling,Christopher M. Barr,Marcia A. Cooper,Jeremy B. Lechman,Daniel Charles Bufford +4 more
TL;DR: In this article, the peridynamic theory of solid mechanics is applied to modeling the deformation and fracture of micrometer-sized particles made of organic crystalline material, and the model is implemented in a three-dimensional, meshless Lagrangian simulation code.
Journal ArticleDOI
Peridynamic elastic waves in two-dimensional unbounded domains: Construction of nonlocal Dirichlet-type absorbing boundary conditions
Arman Shojaei,Alexander Hermann,Pablo Seleson,Stewart A. Silling,Timon Rabczuk,Christian J. Cyron +5 more
TL;DR: In this paper , the authors proposed absorbing boundary conditions (ABCs) derived from a semi-analytical solution of the peridynamics governing equation at the exterior region, made up of a finite series of plane waves, as fundamental solutions (modes), which satisfy the PD dispersion relations.
Journal ArticleDOI
Crack nucleation from non-metallic inclusions in aluminum alloys described by peridynamics simulations
Mohammad Rezaul Karim,Kai Kadau,Santosh B. Narasimhachary,Francesco Radaelli,Christian Amann,Kaushik Dayal,Stewart A. Silling,Timothy C. Germann +7 more
TL;DR: In this article, a peridynamic simulation framework for the description of the crack nucleation process from cluster of non-metallic inclusions in aluminum alloys is presented, where multiple micro-crack nucleation events from individual inclusions, and eventually one micro-Crack dominates.

James V. Cox,Gerald William Wellman,John M Emery,Jakob T. Ostien,John T. Foster,Theresa Elena Cordova,Thomas B. Crenshaw,Alejandro Mota,Joseph E. Bishop,Stewart A. Silling,David John Littlewood,James W. Foulk,Kevin J. Dowding,Kristin Dion,Brad L. Boyce,Joshua Robbins,Benjamin Spencer +16 more
TL;DR: In this paper, the authors provide a double-blind quantitative assessment of several computational capabilities including tearing parameters embedded in a conventional finite element code, localization elements, extended finite elements (XFEM), and peridynamics.
Determination of Ballistic Limit for IM7/8552 Using Peridynamics
TL;DR: In this paper, the authors present simulation results for the ballistic limit (V50) of IM7/8552 composite panels ballistically tested with an impactor representative of a high-velocity fan-blade-out condition.
