A T-300 carbon fiber–epoxy lamina (vf ¼ 0.60) with a fiber orientation angle of 458 is subjected to.

A T-300 carbon fiber–epoxy lamina (vf ¼ 0.60) with a fiber
orientation angle of 458 is subjected to a biaxial stress state of sxx ¼ 100
MPa and syy ¼ 50 MPa. Determine (a) the strains in the xy directions, (b) the
strains in the 1–2 directions, and (c) the stresses in the 1–2 directions. Use
the material property data of Example 3.6.
