1. A composite has the following properties: E1=105 GPa, E2-12 GPa, G12=4.5 GPa, v12=0.12. Create plots of the following variables vs. 0 (0 =0° to 90°). You may use the tool of your choice to create these plots (Excel, Matlab etc). If in MATLAB, also submit the code on Brightspace. If in Excel, include a list of calculated values (in 5 deg increments), along with your on-paper assignment. Hand sketch will not receive any credit a. Ex/E1 b. Ey/E2 c. Gxy/G12 d.

1. A composite has the following properties: E1=105 GPa, E2-12 GPa, G12=4.5 GPa, v12=0.12. Create
plots of the following variables vs. 0 (0 =0° to 90°). You may use the tool of your choice to create
these plots (Excel, Matlab etc).
If in MATLAB, also submit the code on Brightspace.
If in Excel, include a list of calculated values (in 5 deg increments), along with your on-paper
assignment.
