Question

P3.47. An ARALL-4 laminate contains three layers of 2024-T8 aluminum alloy sheet (each 0.3 mm thick) and two layers of 0 unidirectional Kevlar 49-epoxy in an alternate sequence, [A1/0K/A1/0k/A1]. Elastic properties of the aluminum alloy are E=73 GPa and v=0.32, whereas ©2007 by Taylor & Francis Group, LLC. those for the Kevlar layers are E,,-562 GPa, E22=4.55 GPa, V12= 0.456, and G12= 1.85 GPa. The nominal thickness of the laminate is 1.3 mm. Calculate the elastic properties of the ARALL-4 laminate

Explanation / Answer

Solution:

Calculation of shear modulus

Formula

G=E/[2(1+v)]

Where G- Shear modulus

V- poisson ratio

E- Modulus of elasticity

And

Calculation of Bulk modulus

Formula

K= E/[3(1-2v)]

Each player's young's modulus, bulk modulus, shear modulus is given

Calculate accordingly for each layer and then add up the values to get overall elastic property of specified material.
