断裂分析中采用一致关联粘聚律的分布粘聚元法
In this work, Distributed cohesive element (DCE) method is proposed forphenomenological engineering fracture analysis. In DCE method, each node is attributed to onesingle element such that the strong discontinuity in terms of element separation displacement isobtained. Cohesive elements are introduced and a consistently coupled cohesive law describing therelation between cohesive traction and separation displacement is implemented. Based on theuniaxial tensile text, material test and Charpy impact energy test of Q460-C grade high strength steel,the consistently coupled cohesive law for Q460-C is established and calibrated. By comparing theDCE simulation result with the test, the effectiveness and feasibility of the proposed consistentlycoupled cohesive law and DCE method in engineering fracture analysis are shown.1.
