Fracture and failure characterization of materials have been a crucial issue regarding reliable structural design. Stress concentration factors, often determined experimentally and computationally are used to scale the nominal stress in a continuous structure to account for the effect of discontinuity. Stress analysis of a finite length plate employing an elliptical hole subjected to axial tension has been carried out using numerical and experimental method. Aluminum alloy 6061 plate with hole of various ratios (i.e. varying major axis and minor axis) is subjected to room temperature fracture test. The comparison is made between the results obtained from experimental and numerical results. The test of aluminium alloy sheets for fracture mechanism and fracture design provides a reliable test data.
