Abstract

Today, the charpy impact test is required as a general quality control test in various industries. Several industrial standards have been formulated to perform the test accurately. It is important to determine the dynamic fracture energy in the charpy impact test and its relation to the fracture toughness through semi-empirical equations. In the present study, the charpy impact test on AZ31 magnesium alloy with standard ASTM E23 sample size is measured by the effect of groove depth, temperature and angle of groove on fracture energy. Taguchi and L18 arrays have been used to design the experiments and obtain the optimal state according to the number of factors studied. The effect of each input variable on the target parameter was analyzed by using ANOVA and the values of input parameters were extracted to maximize the amount of fracture energy by signal to noise method. The results showed that the groove depth has the greatest effect on the fracture energy and decreased with increasing groove depth. Also the best combination to maximize fracture energy was obtained in the non-grooved sample at -10 °C with a groove angle of 60 °.
