Bulk Modulus is related to Modulus of Elasticity and Poisson's Ratio as. A 1200 kg object is suspended from the end of the rod. To achieve this temper, the metal is solution heat-treated and artificially aged until it meets standard mechanical property requirements. Modulus of Elasticity : 69.0 GPa: Average of Tension and Compression. 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. G = Shear Modulus, also known as Modulus of Rigidity; K = Bulk Modulus = Poisson’s Ratio . 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. Analuminum nail of radius 7.5 × 10–4 m projects 0.035 m horizontally outward froma wall. Shear modulus (elastic shear modulus).
