STUDY OF THE DAMAGE DEGREE OF DENT PIPE BASED ON OYANE DUCTILE FRACTURE CRITERION
The depth of the pipeline depression has different influence on the safety of X60 pipeline steel,combining Oyane ductile fracture criterion with numerical simulation method to study damage degree of the pipeline. Establishing three dimensional spherical concave defect pipeline model by finite elemen...
