Characterization of 2014-T651 Aluminum Alloy

The mechanical properties of 2014-T651 aluminum alloy were determined at room temperature under various strain rates and stress states. Uniaxial tension and compression tests were performed at strain rates ranging from 0.00001 to 1000 sec-1. Biaxial stress tests were conducted at rates of 0.0001 and 1 sec-1. The biaxial stress states were obtained with thin walled tubular specimens loaded with a combination of axial tensioncompression, internal pressure, torsion and external pressure with any two loads superimposed for any given test. The experimentally observed yield agrees with the von Mises yield condition. Strain to failure exhibited a high degree of anisotropy ductility being minimum in the thickness direction. Fracture toughness and pin bearing strength properties were also determined.
