Artificial neural network modelling of cold‐crack resistance of high strength low alloy steel 950A

The Journal of Engineering, Volume 2019, Issue 2, Page 447-454, February 2019., 2019
The objective of the study is to predict the cold cracking resistance of high strength low alloy 950A welded joints using an artificial neural network (ANN) model. A bead on plate welding is carried out using the gas metal arc welding process. The identified process parameters for the ANN are preheating temperature, oxide particle content, and heat ...

Failure Assessment for the High‐Strength Pipelines with Constant‐Depth Circumferential Surface Cracks

Advances in Materials Science and Engineering, Volume 2018, Issue 1, 2018., 2018
In the oil and gas transportation system over long distance, application of high‐strength pipeline steels can efficiently reduce construction and operation cost by increasing operational pressure and reducing the pipe wall thickness. Failure assessment is an important issue in the design, construction, and maintenance of the pipelines.

Full‐Scale Experimental Verification of the Explosion Shock Wave Model of a Natural Gas Pipeline

Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018
As developments in natural gas pipelines increasingly incorporate higher grades of steel, larger diameters, and higher pressures, the consequences of an accident caused by leakage, explosion, or ignition become progressively more severe. Currently, major technical obstacles include the quantification of the impact of an explosion shock wave of a high ...
