Abstract
A method is presented that describes the selection of a multiaxial or a uniaxial testing procedure to validate fuel tank strap durability. Strain gage rosette data recorded from a proving ground schedule were used to determine the loading experienced on the fuel tank strap. Representative testing was conducted using both multiaxial and uniaxial testing procedures. This method utilizes advanced durability software and fatigue analysis to evaluate both multiaxial and uniaxial laboratory test results. The method establishes a set of criteria for the selection of multiaxial or uniaxial durability test procedures.
