Abstract

Accurate prediction for fatigue crack propagation path is crucial for ensuring the safe operation of pipelines. In this paper, we present a novel method for predicting fatigue crack propagation path of surface cracks in pipelines with a ConvLSTM-based model. The ConvLSTM-based model effectively correlates crack propagation paths with fatigue cycles. Moreover, we have improved the method which transforms simulation results into the dataset for machine learning. The prediction results prove the excellent predictive power of the improved method. To further validate the robustness of our model, we test its predictive capabilities on cases not included in the dataset. The proposed method accurately forecasts the fatigue crack propagation path in pipelines without requiring re-modeling and re-computational attempts. The result indicates that the proposed method significantly reduces computational time compared to the finite element method.

期刊介绍： Pressure vessel engineering technology is of importance in many branches of industry. This journal publishes the latest research results and related information on all its associated aspects, with particular emphasis on the structural integrity assessment, maintenance and life extension of pressurised process engineering plants. The anticipated coverage of the International Journal of Pressure Vessels and Piping ranges from simple mass-produced pressure vessels to large custom-built vessels and tanks. Pressure vessels technology is a developing field, and contributions on the following topics will therefore be welcome: • Pressure vessel engineering • Structural integrity assessment • Design methods • Codes and standards • Fabrication and welding • Materials properties requirements • Inspection and quality management • Maintenance and life extension • Ageing and environmental effects • Life management Of particular importance are papers covering aspects of significant practical application which could lead to major improvements in economy, reliability and useful life. While most accepted papers represent the results of original applied research, critical reviews of topical interest by world-leading experts will also appear from time to time. International Journal of Pressure Vessels and Piping is indispensable reading for engineering professionals involved in the energy, petrochemicals, process plant, transport, aerospace and related industries; for manufacturers of pressure vessels and ancillary equipment; and for academics pursuing research in these areas.
