AB  - The aim of this paper was to numerically simulate the plastic behavior of a three-material body specimen and compare the results with physical experiments performed on the same specimen. Both the physical and numerical models were subjected to tensile load which lead to the forming of a neck in the specimen due to significant plastic strain. Specimens were made by welding two materials, steel M (ferrite) and steel X (austenite) using filler metal with yield strength higher than the other two materials, producing the overmatched welded joint. Plastic behavior of the specimen was simulated using the finite element method (FEM). As for the physical experiment, in addition to tensile tests of the three-material body specimen, each material was tested individually in order to obtain stress-strain diagrams. These diagrams were then used to determine the input parameters required for the numerical simulation of plastic strain. The results have confirmed that FEM can be used to effectively and accurately simulate the plastic behavior of a specimen made of three different materials.
