DETERMINATION OF SELECTED MIL-HDBK-5 DESIGN ALLOWABLE PROPERTIES FOR FIVE AEROSPACE MATERIALS - Annual Report (15 Feb 74 to 15 Feb 75)

Abstract:
THIS ANNUAL REPORT DESCRIBES A TEST PROGRAM TO DEVELOP CERTAIN MISSING MIL-HDBK-5 DESIGN ALLOWABLE PROPERTIES FOR FIVE AEROSPACE MATERIALS: 2024-T861 ALUMINUM ALLOY SHEET, 17-4PH AND 15- 5PH PRECIPITATION HARDENING STAINLESS STEEL BAR, 9NI-4CO-0.20C STEEL PLATE, AND TI-6AL-6V-2SN ANNEALED EXTRUSION. DESIGN ALLOWABLE PROPERTIES WERE DETERMINED IN ACCORDANCE WITH MIL-HDBK-5 GUIDELINES. MECHANICAL PROPERTIES DETERMINED WERE TENSILE YIELD STRENGTH; TENSILE ULTIMATE STRENGTH; COMPRESSIVE YIELD STRENGTH; SHEAR ULTIMATE STRENGTH; BEARING YIELD STRENGTH; BEARING ULTIMATE STRENGTH; COMPRESSIVE MODULUS OF ELASTICITY; POISSONS RATIO; STRESS-STRAIN CURVES; STRESS-TANGENT MODULUS CURVES, AND HIGH TEMPERATURE PROPERTIES. TERMS: MPDC, DESIGN ALLOWABLES, ALUMINUM ALLOYS, 2024-T861, SHEET, STAINLESS STEEL, 17-4 PH, 15-5 PH, BARS, ENGINEERING STEEL, 9NI-4CO-0.20C, PLATE, TITANIUM ALLOYS, TI-6AL-6V- 2SN, EXTRUSIONS, TENSILE YIELD STRENGTH, ULTIMATE TENSILE STRENGTH, COMPRESSIVE YIELD STRENGTH, SHEAR ULTIMATE STRENGTH, BEARING ULTIMATE STRENGTH, BEARING YIELD STRENGTH, MODULUS OF ELASTICITY, POISSONS RATIO, STRESS STRAIN DATA, TEMPERATURE EFFECT.;
