Mechanical Properties of Stress-Relieved Stretched Aluminum Alloy Plate

摘要

Ratios of tensile, compressive, shear and bearing properties to corresponding long-transverse tensile properties were computed. Some variations in ratios occur with respect to alloy, temper, thickness, location in thickness, and direction of loading. Groups of ratios for each alloy in the -TX51 tempers were analyzed statistically. Minimum-average values were determined. Using these minimum-average values, together with long-transverse tensile properties from 5xsisspecifications as basis A values and corresponding basis B values obtained from recent production data, tables of design mechanical properties of MIL-HDBK-5 were prepared. Tensile and compressive stress-strain characteristics were determined. Typical and minimum stress-strain and compressive tangent-modulus curves were prepared for MILHDBK-5. (Author)
