“…Although the CPM originally used enrichments to describe crack surfaces, which is similar to some enrichment‐type methods for meshless fracture , it has been shown that extra unknowns caused by enrichment can be removed by splitting cracking particles as in . A number of papers have appeared recently applying CPM to dynamic fracture , the use of obscuration zones and ductile fracture , and in , some issues associated with integration have been addressed using stabilised nodal methods. There are also a few manuscripts using cracking particle‐type methods for other fracture problems, such as the use of cohesive zone elements and cohesive links .…”

SUMMARY (TO BE REVISED ONCE TEXT IS COMPLETE) An adaptive Cracking ParticleMethod is developed to model the crack propagation process. A set of cracking particles are used to describe the crack patterns and can be easily updated when the crack propagates. The change of cracking angle is recorded in discrete segments of broken lines which makes this methodology suitable to model discontinuous cracks. The node arrangements can be set up automatically by the adaptivity approach throughout the whole propagation steps to keep the accuracy and efficiency of the analysis. The system stiffness is calculated and stored in local matrices, so only a small influenced domain should be recalculated for each step while the remainder can be read directly form the storage, which greatly reduces the computational expense. The methodology is applied to several 2D crack problems and good agreements are achieved

“…It was later shown that these enrichments can be removed by splitting the cracking particles into two new particles [39]. This CPM has been applied to static fracture [37], dynamic fracture [24,25] and ductile fracture [23]. There are also some papers using cracking-particletype methods for fracture modelling [15,49].…”
