Abstract

The present investigation deals with the optimization of the parameters for better formability behaviour of brass sheet metal under uniaxial isothermal Tensile Test by using Taguchi Design of Experiments (DoE). The standard L₉ (3³) Orthogonal Array was formulated to run the experiments based on Taguchi robust design and accordingly uniaxial isothermal Tensile Test conducted at orientation (0⁰, 45⁰ and 90⁰), temperature (300°C, 400°C, and 500 °C), and strain rate (0.001, 0.01 and 0.1 s⁻¹). Analysis of S/N ratios for Ultimate tensile strength and % elongation reported the optimum condition as orientation at level 1 (in degrees), temperature at level 1(in degree Celsius), and strain rate at level 3 (s^-1) and orientation at level 1 (in degrees), temperature at level 3 (in degree Celsius), and strain rate at level 1 (s^-1) respectively. ANOVA analysis reported the Temperature as the most significant parameter and its contribution are about 62.109% and 71.924% for ultimate tensile strength and % elongation respectively.
