TL;DR: The scaled boundary finite-element method, alias the consistent infinitesimal finite element cell method, is developed in this paper starting from the governing equations of linear elastodynamics and converges to the exact solution in the finite element sense in the circumferential directions.

TL;DR: The scaled boundary finite element method as mentioned in this paper is a semi-analytical fundamental-solutionless boundary-element method based solely on finite elements, which is used to solve the wave propagation problem.

TL;DR: In this paper, the LCH-CONF-1998-009 Record created on 2007-04-24, modified on 2016-08-08, was used as a reference.

TL;DR: An automatic crack propagation modelling technique using polygon elements is presented in this article, where a simple algorithm to generate a polygon mesh from a Delaunay triangulated mesh is implemented The polygon element formulation is constructed from the scaled boundary finite element method (SBFEM), treating each polygon as a SBFEM subdomain and is very efficient in modelling singular stress fields in the vicinity of cracks.

TL;DR: The scaled boundary finite element (SDFE) method as discussed by the authors is a semi-analytical boundary-element method based on finite elements, which is applied to fracture mechanics problems, but only the actual boundary of the body, but not the straight crack faces and material interfaces passing through the crack tip, is spatially discretized with finite elements.
