Abstract: Since, stainless steel, aluminum and bronze as a single material are directly connected with safety as the materials most universally employed, sufficient advance experiments before use are an essential requirement. Based on such point, notch tensile analysis with simulation was conducted in the present study by designing notched tensile specimen models of the same specification for stainless steel, aluminum and brass. In the present study, notched tensile specimen models made of stainless steel, aluminum and brass were subjected to 3D modelling using CATIA design program for which notched tensile analysis in simulation was performed. By designing notched tensile specimen models per material and conducting a notch tensile analysis, tensile strength characteristic and durability of each material could be affirmed. According to the results of conducting the notched tensile analysis, the loads were shown to have tendency for gradual increase until the maximum load was exhibited in the case of aluminum notched tensile specimen model and brass notched tensile specimen model. In the case of stainless steel tensile specimen model, the loads were rapidly increased until the forced displacement progressed by about 3 mm followed by tendency for gradual increase shown subsequently. This study is aimed at notch tension of universally employed materials such as stainless steel, aluminum and brass among materials to identify material properties of heterogeneous materials and composite materials it is considered that the data secured through the relevant study can be utilized as basic data for the investigations to be conducted in the future.
