Abstract

This study aimed at clarifying whether the fatigue life of stainless steel elbow pipes is the same as that of specimens subjected to uniaxial cyclic loading. The fatigue test under in-plane cyclic displacement was conducted for a stainless steel 100A elbow pipe using six specimens. Since the strain range was a key parameter for the fatigue damage assessment, it was carefully identified in the fatigue test using a digital image correlation technique in addition to strain gauges. Finite element analyses were conducted to estimate the equivalent strain range at the crack initiation point from the measured strain range. Comparison of this fatigue life with that obtained by the fatigue tests for uniaxial loading conditions using specimens taken from an elbow pipe of the same heat indicated there was no reduction in the fatigue life of the elbow pipe for the same equivalent strain range.

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.
