1. Explain in detail the Hill’s concentration factors approach.

2. What are Reuss and Voigt approximations in connection with Hill’s concentration factors approach?

3. For fibre volume fraction of 0.6, determine all the effective mechanical properties for the fibre and matrix materials given in Table 7.1 and Table 7.2 and compare them with the experimental effective properties as reported in Soden et al [7]. Calculate percentage difference for all properties. Use Voigt and Reuss approximation for this exercise.
