Abstract

This study uses experimental and numerical methods to examine the impact of average fatigue force, amplitude fatigue force, and internal pressure on the ratcheting behavior of SS316L concentric and eccentric reducers. The material of the samples was first verified through mechanical analyses. Subsequently, the samples were fatigue tested at controlled force and room temperature (25 °C), and strain reading was done at the critical points of the samples by the digital image correlation (DIC) method. Numerical simulations with Abaqus software were conducted to validate the experimental results, confirming the experimental tests' accuracy with an acceptable margin of error. Finally, after ensuring the reliability of the numerical results, the influence of the changes in the parameters mentioned above was numerically investigated. It was observed that as these variables increase, the ratcheting strain also increases in the axial and circumferential directions, with greater sensitivity to the increase in average force and amplitude force.

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.
