DUCTILE DAMAGE CHANGE ANALYSIS OF AXIAL SIMPLE DENTED PIPELINE IN CONSTRUCTION STAGE
Mechanical damage can cause immediate or delayed failure of the pipe. The dent is the main form of mechanical damage. According to the Oyane ductile fracture criterion, the finite element method was used to simulate the axial simple dent caused by the construction stage. Analyzed the change of pipel...
