- Abstract
To investigate relationship between the notch and fracture pressure,set up 2D element model of pulse separation device,calculated the distributing of its stress field,simulated its fracture course,performed tests of PSD with different deep prefab notch.Comparisious were made between simulation and tests,they were consistent with each other.The results show that,the fracture pressure of PSD has a linear relationship with the value for effect thickness of PSD divided by depth of prefab notch.
