Consider an orthotropic e-glass /epoxy composite cube of dimensions 100 mm x 100 mm x100 mm. The cube is subjected to an extension in the 2 direction of 0.5mm and is constrained against contraction in the 3 direction. Calculate the stress and strains in all the principal directions. E1=207 GPa, E2=E3=5.6 GPa G12=4.1GPa G23=G13=1.7GPa v12=0.23 v23=v13=0.43
