Abstract

This paper presents some experimental results of cyclic tests at room temperature in the elastic/inelastic regimes of an AISI 304 stainless steel elbow, which was subjected to in-plane closing and opening bending. The purpose of the work is the analysis of fittings subjected to a specific history of load/deflection in order to verify the correct prediction of the strain/stress state by means of stress intensification factors with the help of standards or elaboration by computer codes. A comparison with numerical data, from a large intensive computer analysis, is not the subject of this paper.standards or elaboration by computer codes. A comparison with numerical dat The experimental activities reported here have been performed in the framework of a research program supported by the Italian Electricity Board (ENEL-CRTN).
