Peridynamic Thermo-Mechanical Modeling of Cracking in Tungsten under Fusion-Relevant Heat Fluxes
Rinkle Juneja, Pablo Seleson, Samuel Temple Reeve +2
Plasma-facing materials (PFMs) are the primary armor materials in fusion reactors, protecting reactor wall components from extreme heat fluxes, energetic particles, and intense neu…

Bond failure in peridynamics: Nonequivalence of critical stretch and critical energy density criteria
Pablo Seleson, Pablo Raúl Stinga, Mary Vaughan
This paper rigorously analyzes bond failure in the peridynamic theory of solid mechanics, which is a fundamental component of fracture modeling. We compare analytically and numeric…
