Abstract

Contruction of materials requires special properties in each part, although in the mechanical properties of the manufacturing process of the metal have been predicted. Therefore, now many tests are carried out on sample of the material. The specimens used are aluminium series 1xxx and 3xx.x. Tensile testing was carried out using a notch (U) with a noctch length (L)±5mm. Notches making used a file and sandpaper. The fracture performance calculation method used the ImageJ application. The calculation results showed that the fracture value (W) of 1xxx aluminum series(6.96 kJ/m 2 ) was greater than that of 3xx.x aluminum series (2.30 kJ/m 2 ). The value of the stress consentration factor (KN) of 1xxx (3,22) aluminum series was greater than that of 3xx.x (3.15) aluminum series. Based on the calculation of fracture (W) and stress concentration factor (KN) it could be concluded that 1xxx aluminum series is more resilient than 3xx.x series aluminium.
