--- res: bibo_abstract: - "We present a method for simulating brittle fracture under the assumptions of quasi-static linear elastic fracture mechanics (LEFM). Using the boundary element method (BEM) and Lagrangian crack-fronts, we produce highly detailed fracture surfaces. The computational cost of the BEM is alleviated by using a low-resolution mesh and interpolating the resulting stress intensity factors when propagating the high-resolution crack-front.\r\n\r\nOur system produces physics-based fracture surfaces with high spatial and temporal resolution, taking spatial variation of material toughness and/or strength into account. It also allows for crack initiation to be handled separately from crack propagation, which is not only more reasonable from a physics perspective, but can also be used to control the simulation.\r\n\r\nSeparating the resolution of the crack-front from the resolution of the computational mesh increases the efficiency and therefore the amount of visual detail on the resulting fracture surfaces. The BEM also allows us to re-use previously computed blocks of the system matrix.@eng" bibo_authorlist: - foaf_Person: foaf_givenName: David foaf_name: Hahn, David foaf_surname: Hahn foaf_workInfoHomepage: http://www.librecat.org/personId=357A6A66-F248-11E8-B48F-1D18A9856A87 - foaf_Person: foaf_givenName: Christopher J foaf_name: Wojtan, Christopher J foaf_surname: Wojtan foaf_workInfoHomepage: http://www.librecat.org/personId=3C61F1D2-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-6646-5546 bibo_doi: 10.1145/2766896 bibo_issue: '4' bibo_volume: 34 dct_date: 2015^xs_gYear dct_language: eng dct_publisher: ACM@ dct_title: High-resolution brittle fracture simulation with boundary elements@ ...
