- •
We study on the ductile damage of the pipeline with type II plain dent.
- •
Oyane ductile fracture criterion is used to dispose the results of finite element.
- •
A specific expression of dent depth and the damage degree of pipeline is obtained.
- •
The influence law of parameters change on the damage degree of pipeline is acquired.
