15 صفحه اولNumerical study of strength mismatch in cross-weld tensile testing
The strength mismatch effect on the deformation behaviour of defect-free cross-weld tensile specimens, where there is a variation in strength along the length of the specimen, was investigated through 2D finite element analysis. A simple bi-material model, which is generally used in current engineering assessments (e.g. R6 “Assessment of the integrity of structures containing defects”) to exami...
متن کاملTensile and Creep Testing of Sanicro 25 Using Miniature Specimens
Tensile and creep properties of new austenitic steel Sanicro 25 at room temperature and operating temperature 700 °C were investigated by testing on miniature specimens. The results were correlated with testing on conventional specimens. Very good agreement of results was obtained, namely in yield and ultimate strength, as well as short-term creep properties. Although the creep rupture time was...
متن کاملExperimental and numerical study of strength mismatch in cross-weld tensile testing
The mechanical properties of welded boiler tubes used in power plants can be significantly altered as a result of the fabrication history, such as pre-straining and heat treatment. The primary aim of the study was to determine the effect of fabrication history on local tensile properties across the welds. This was achieved by testing cross-weld specimens machined from welded thin-walled tubes (...
متن کاملTensile Testing of Abalone Nacre Miniature Specimens Using Microscopy and Speckle Correlation
Nacre from seashells, also known as mother-of-pearl, has attracted much attention for its remarkable mechanical properties despite the structural weaknesses of its components [1],[2]. In this article, in situ-tensile tests of dry and wet nacre dogbone specimens are presented. Optical microscopy and digital image correlation techniques were used to determine deformation and strain fields . While...
