Compute the values of and ı in equations (3.30a) and (3.30b)
using the material properties of the fiber and matrix for a
graphite-reinforced composite and show that these quantities are
small compared to unity. Show this for the range 0:15 V f 0:75. The
material properties are given in equations (3.2) and (3.3).
