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."}],"date_created":"2018-12-11T11:53:09Z","doi":"10.1145/2766896","title":"High-resolution brittle fracture simulation with boundary elements","conference":{"start_date":"2015-08-09","name":"SIGGRAPH: Special Interest Group on Computer Graphics and Interactive Techniques","end_date":"2015-08-13","location":"Los Angeles, CA, United States"},"department":[{"_id":"ChWo"}],"status":"public","issue":"4","scopus_import":1,"related_material":{"record":[{"status":"public","id":"839","relation":"dissertation_contains"}]},"project":[{"name":"Efficient Simulation of Natural Phenomena at Extremely Large Scales","grant_number":"638176","_id":"2533E772-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"oa_version":"Submitted Version","volume":34,"citation":{"ista":"Hahn D, Wojtan C. 2015.
