THE MECHANICAL BEHAVIOR OF LABORATORY CROSS-WELD  SPECIMEN AND ITS RELATION WITH THE PRACTICAL  CASES AT ELEVATED TEMPERATURE

Abstract

Abstract: In order to interpret the test results of crossweld specimens for application in practical welded components, the present paper studies the high temperature behavior of laboratory cross weld specimens in terms of the uniaxial material tests and numerical simulations. It is found that the crossweld specimen may be used for the high temperature strength assessment, but can hardly be used for life assessment of the practical welded components, which depends on the loading conditions of the components.

Key words: high temperature, welding, geometrical effect, constitutive equation, life prediction
