Abstract
In this paper, the non-linear analyses of beam deflection were used to calculate the modulus of elasticity of stainless steel ( grade 410) beams that exposed to heating and then cooling with different rate. Several specimens of alloy steel were heated to temperature above critical temperature AC3 at iron-carbon diagram (about 920Co) and then cooling with different cooling rate by using various cooling media. The cooling rates were (0.11, 1.2, 17, 77 and 150oC/Sec). In order to measure the modulus of elasticity of these specimens, the linear and non-linear analysis (using ANSYS V.14 Software) for calculating the deflection of beam are used in additional to experimental results of maximum deflection of beam. From the theoretical and experimental results of maximum deflection of beam, the modulus of elasticity of the specimens were calculated using statistical method and then compared the results with the experimental results from tensile stress. For calculating the modulus of elasticity, the experimental results of maximum deflection of beam at different applied load were recorded and the modulus of elasticity calculated. A very good agreement between experimental and theoretical results and the maximum error was (8%).
