The ratio of shear stress and shear strain is called shear modulus. The shear modulus of aluminium is 3. Shear Strength = 330 MPa. 2, 1052-1055 (1985)]. With the exception of Ni in the temperature range below the Curie point, linear behavior was found for all three metals. The modulus of elasticity for 7075 aluminum is 71.7 GPa (10,400 ksi), and it's shear modulus is 26.9 GPa (3900 ksi) (see Table 1 for a summary). The shear modulus (G), elastic modulus (E) and Poisson's ratio (v) are related by: G = E/(2(1+v)) It's usually easier to find the elastic modulus (69 GPa) for aluminum and Poisson's ratio (0.33) than the shear modulus. The shear modulus describes the material’s response to shearing strains. Simple expressions for upper and lower limits to the shear modulus of honeycomb sandwich cores are obtained by application of the Unit Displacement and Unit Load methods in conjunction with simplifying assumptions as to the strain and stress systems respectively in the core. Shear modulus' derived SI unit is the pascal (Pa), although it is usually expressed in gigapascals (GPa) or in thousands of pounds per square inch (ksi). The ASTM Bending values had the highest COVs, while the ASTM Torsion had the lowest COVs. Aluminum 2024-T3. shear strength aluminum .
