A composite has the following properties: $E_1=105$GPa,$E_2=12$GPa,$G_{12}=4\mathrm{.}5$GPa,$v_{12}=0\mathrm{.}12.$ Create

plots of the following variables vs$.$ to $\{$:$90).$ You may use the tool of your choice to create

these plots $($Excel$,$ Matlab etc$).$

If in Excel, include a list of calculated values $($in $5$ deg increments$),$ along with your on$-$paper

assignment.

a$.\frac{E_x}{E_1}$

b$.\frac{E_y}{E_2}$

c$.\frac{G_{xy}}{G_{12}}$

d$.\frac{v_{xy}}{v_{12}}$

e$.\frac{{}_{xs}}{E_x}$

Repeat problem $1$ but for a woven composite lamina with $E_1=E_2=55$GPa,$G_{12}=8$GPa,$v_{12}=0\mathrm{.}02.$

You can use the same equations $($Eq$.4\mathrm{.}81$ from the book$).$

For each of these plots, comment on how it differs from the corresponding one in problem $1.$ Be

clear but brief $($i$.$e$.1-2$ sentences$)$
