Calculate the effective laminate moduli for the two laminates, i$.$e$.$ Exx$(1)$ and Exx$(2),$ use this to determine the ratio

Exx$(2)$Exx$(1)$

where layup $1$ defining Exx$(1)$ is

$[-60,60,0,45,60,90,90,60,45,0,60,-60]$

and layup $2$ defining Exx$(2)$ is

$[-45,90,0,90,45,-30,-30,45,90,0,90,-45]$

Assume a material with properties

E$11=43\mathrm{.}00$ GPa

E$22=8\mathrm{.}90$ GPa

G$12=4\mathrm{.}50$ GPa

plyt $=0\mathrm{.}150$ mm

$=0\mathrm{.}27$
