The SG of fiber-reinforced composites can be  represented as shown below.[[BR]]
[[Image(Problem-2-SG.jpg)]][[BR]]
Let the material properties of the fiber and matrix be:
Fiber: E,,11,, =230 GPa, E,,22,, =15 GPa, G,,12,,=G,,13,, =15GPa, G,,23,, =7GPa, v,,12,,=v,,13,, =0.2000 
ν,,23,, =0.0714.

Matrix: E =4.0GP, ν=0.35 

Fiber volume of fraction is assumed to be 60%
The material properties are obtained from:
“Soden, P. D., Hinton M. J. and Kaddour, A. S., Lamina properties, lay-up configurations and loading conditions for a range of fibre reinforced composite laminates. Compos. Sci. Technol., 1998, 58(7), 1011”[[BR]]
