TL;DR: In this article, two different approaches for modeling the behavior of carbon nanotubes are presented, one based on homogenization and the other based on finite element models, where the interatomic interactions due to covalent and non-covalent bonds are replaced by beam and spring elements, respectively, in the structural model.

TL;DR: In this paper, a phase field model for void formation in metals with vacancy concentrations exceeding the thermal equilibrium values is presented, which allows for a unified treatment of void nucleation and growth under the condition of random generation of vacancies, which is similar to vacancy generation by collision cascade in irradiated materials.

TL;DR: In this paper, a phase-field model of void formation and evolution in irradiated metals by spatially and temporally evolving vacancy and self-interstitial concentration fields is presented, which captures the processes of point defect generation and recombination, annihilation of defects at sinks, as well as void nucleation and growth in the presence of grain boundaries.

TL;DR: In this paper, the structural features of the generated a-C models were investigated in terms of pair correlation functions, bond-angles, pore-size distribution and carbon hybridization content.

TL;DR: In this article, a phase-field model for void formation in polycrystalline metals with vacancy concentrations exceeding the thermal equilibrium values is presented, which captures several relevant processes including vacancy annihilation and nucleation at grain boundaries (GBs), vacancy diffusion toward sinks (including GBs and void surfaces) as well as void nucleation and growth due to vacancy supersaturations occurring in the grain interiors.
