WebApr 3, 2015 · Abstract. Fluid catalytic cracking (FCC) particles account for 40 to 45% of worldwide gasoline production. The hierarchical complex particle pore structure allows access of long-chain feedstock molecules into active catalyst domains where they are cracked into smaller, more valuable hydrocarbon products (for example, gasoline). WebNov 27, 2013 · A stable cracking particles method (CPM) based on updated Lagrangian kernels is proposed. The idea of CPM is to model the crack topology by a set of cracked particles. Hence no representation of the crack surface is needed making the method useful for problems involving complex fracture patterns as they occur in dynamics and …
WebDec 7, 2004 · A new approach for modelling discrete cracks in meshfree methods is described. In this method, the crack can be arbitrarily oriented, but its growth is represented discretely by activation of crack surfaces at individual particles, so no representation of the crack's topology is needed. The crack is modelled by a local enrichment of the test and …
