Abstract The effect of geometry (notch shape, specimen size) and materials heterogeneity (mismatching in welded joint) on the Charpy specimen behaviour is analysed in the paper. Two- and three-dimensional stress analyses by finite element method (FEM) are applied in solving this problem, thus providing stress-fields and plastic deformation distribution in specimen, and presenting its behaviour. Keywords: heterogeneity of welded joint, matching effect, finite element method, stress analyses, standardized Charpy testing, subsized Charpy specimen |
