| Summary: | In this report, the study on the fracture behaviour of aluminium alloy 6061 by using experimental testing and finite element analysis simulation was investigated. The
experiments were carried out by using thin aluminium sheet with the thickness of 1.5 mm. The aluminium sheet were cut into dog-bone specimen according to ASTM E8/E8M and notch was applied on certain sample. This experimental study was focused on the tensile properties and fracture behaviour of dog-bone without notch, V-notch, and U-notch specimen. The Vickers hardness test and tensile test were applied to evaluate the hardness
measurements and tensile strength for aluminium alloy 6061 respectively as well as the microstructure analysis for the fracture behaviour. The results showed the dog-bone without notch exhibited higher tensile strength and maximum force compared to V-notch and U-notch specimen. Microstructure analysis on the fracture surface for each specimen was observed by using scanning electron microscope revealed that all three types of specimens were fractured in ductile mode. The difference was the dimple formation in fractured surface of dog-bone without notch could be easily recognized compared to fractured surface of V-notch and U-notch specimen in higher magnification. Both notched specimen exhibits the similar fractured surface image. The finite element analysis
simulation is done by using ANSYS Workbench 16.0 for each type of specimen in which non-linear simulation was applied. The comparison between experimental values and
simulation showed that for dog-bone without notch the value obtained were almost the same. However, there were a large difference between experimental and simulation value for V-notch and U-notch specimen. |
