Fracture Nucleation in Single-Wall Carbon Nanotubes Under Tension: A Continuum Analysis Incorporating Interatomic Potentials
TL;DR: In this article, a continuum theory of fracture nucleation in single-walled carbon nanotubes was developed by incorporating interatomic potentials between carbon atoms into a continuum constitutive model for the nanotube wall.
A finite element method to compute three-dimensional equilibrium configurations of fluid membranes
Ramsharan Rangarajan,Huajian Gao +1 more
TL;DR: A systematic algorithm for computing large deformations, wherein solutions at subsequent load steps are identified as perturbations of previously computed ones, and a Galerkin finite element method is used to compute discrete C 1 approximations of the normal offset coordinate.
Dislocation core spreading at interfaces between metal films and amorphous substrates
TL;DR: In this paper, the authors developed a number of mathematical solutions for dislocation core spreading at an incoherent interface between a metal thin film and an amorphous substrate, where they considered screw dislocations and considered the interface to be characterized by a shear adhesive strength, τ 0, below which no core spreading occurs, and above which spreading takes place in a viscous manner.
A rate-dependent cohesive continuum model for the study of crack dynamics
TL;DR: In this paper, a rate-dependent cohesive continuum model is developed to represent material particles interacting in a viscous medium, where the interactions between material particles are modeled using a cohesive force law while microstructural resistance to relaxation is represented by a phenomenological continuum viscosity function.
