Quantitative prediction of fracture toughness (KIc) of polymer by fractography using deep neural networks

, 2022
Fracture surfaces provide various types of information about fracture. The fracture toughness $${K_{{\rm{I}}c}}$$, which represents the resistance to fracture, can be estimated using the three-dimensional (3D) information of a fracture surface, i.e.

Failure Analysis of 316L Air Cooler Stainless Steel Tube in a Natural Gas Production Field

International Journal of Electrochemical Science, 2015
In spite of the excellent resistance of stainless steel (SS) towards uniform corrosion, overcoming various localized corrosion could be a real challenge. This work presents an analysis of the failure behavior of 316L SS air chiller tube with a peripheral
