Abstract : This report presents an experimental investigation into the tension and compression behavior of a plate specimen with a angled elongated hole. This specimen type will be used for validation of three life management options on the F-111 wing pivot fitting (DADTA, cold expansion/interference fit plug and stress bridge). Two different brands of strain gauges were used to determine their suitability for use in regions of high plastic strains. The buckling load capability of the plate specimen was determined and found to be suitable for further validation tests.
