Design Mechanical Properties Including Fracture Toughness and Fatigue, Fatigue Crack Propagation Rates and Corrosion Characteristics of Alclad 7050-T76 Sheet.

Abstract

The tensile, compressive, shear, bearing, fracture toughness and axial-stress fatigue properties, fatigue-crack propagation rates and corrosion characteristics have been determined for 10 lots of alclad 7050-T76 sheet ranging from 0.025-in. through 0.249-in. thick. Tables of computed design mechanical properties and individual tensile and compressive stress-strain curves are presented. The effect of stretching on the tensile properties was also studied. Axial-stress fatigue strengths and fatigue-crack propagation rates were determined in ambient-air and salt-fog environments.
