Energy release rate approximation for small surface-breaking cracks using the topological derivative
The topological derivative provides the variation of a response functional when an infinitesimal hole of a particular shape is introduced at a point of the domain. In this fracture mechanics work we use the topological derivative to approximate the energy release rate field associated with a small crack at any boundary location and at any orientation. Our proposed method offers significant comp...
متن کاملEnergy release rate for non smooth cracks in planar elasticity
This paper is devoted to the characterization of the energy release rate of a crack which is merely closed, connected, and with density 1/2 at the tip. First, the blow-up limit of the displacement is analyzed, and the convergence to the corresponding positively 1/2-homogenous function in the cracked plane is established. Then, the energy release rate is obtained as the derivative of the elastic...
متن کاملShape and topological sensitivity analysis in domains with cracks
Framework for shape and topology sensitivity analysis in geometrical domains with cracks is established for elastic bodies in two spatial dimensions. Equilibrium problem for elastic body with cracks is considered. Inequality type boundary conditions are prescribed at the crack faces providing a non-penetration between the crack faces. Modelling of such problems in two spatial dimensions is pres...
متن کاملInteracting Surface States of Three-Dimensional Topological Insulators.
We numerically investigate the surface states of a strong topological insulator in the presence of strong electron-electron interactions. We choose a spherical topological insulator geometry to make the surface amenable to a finite size analysis. The single-particle problem maps to that of Landau orbitals on the sphere with a magnetic monopole at the center that has unit strength and opposite s...
متن کاملThree-Dimensional Topological Insulators
Topological insulators in three dimensions are nonmagnetic insulators that possess metallic surface states (SSs) as a consequence of the nontrivial topology of electronic wavefunctions in the bulk of the material. They are the first known examples of topological order in bulk solids. We review the basic phenomena and experimental history, starting with the observation of topological insulator b...
