Publication number: 20140372060Abstract: A calibration method for brittle fracture assessment parameters for pressure vessel materials based on the Beremin model includes selecting at least two types of specimens of different constraints, and calculating the fracture toughness values K0 corresponding to 63.2% failure probability for each type of specimens at a same calibration temperature by using the respective fracture toughness data. The method proceeds by obtaining the stress-strain curve of the material at the calibration temperature, generating finite element models for each type of specimens, and calculating the maximum principal stress and element volume of every element at K=K0 in each model. A series of values of m are assumed to compute a group of ?u values for each type of specimens, and then m˜?u curves are plotted for each type of specimens. Brittle fracture assessment parameters are then determined for the material according to the coordinates of the intersection of the m˜?u curves.Type: ApplicationFiled: November 27, 2012Publication date: December 18, 2014Applicant: East China University of Science and TechnologyInventors: Fuzhen Xuan, Yupeng Cao, Hu Hui, Penning Li, Guozhen Wang
