Chapter 1
Page 27: Figure 1.7 (b), the vertical axis and the legend for the solid line should be E2/E1 instead of E2/Ef .
Chapter 2
Page 41: The S12 term in Equation (2.2.9) is given as 1-n/E . It should be S12 = -n/E .
Page 75: In Example 2.4.2, material properties given in the statement are for Graphite/Epoxy not for Glass/Epoxy. The correct properties for Glass/Epoxy are: E1= 38.6 GPa, E2 = 8.27 GPa, G12 = 4.14 GPa, and n12 = 0.26.
Page 78: Figure 2.14. The curve labeled -B26 should be either B26 or -B16 .
Page 79: The A66 term in Equation (2.4.38) should be 159.5 instead of -23.07.
Chapter 4
Page 136: The objective function should read, f(x) = h = n t (x1 + 4x2 + 8x3)
Page 137: The the constraint on Young modulus is 2.5 - n t (x1 + 4x2 + 8x3) (18.5x1 + 3.176x2 + 7.552x3) £ 0 [appears in two places towards the bottom of the page]. Also, the constraint on the shear modulus is 0.5 - n t (x1 + 4x2 + 8x3) (0.93x1 + 4.858x2 + 2.894x3) £ 0 [This also appears on top of page 138].
Page 145: Four lines above Eq. 4.2.11, "line DE" should be "line DC".
Page 166: Exercise 2. The problem in its present form does not have a feasible solution. Add the following to the problem definition: "with the same requirements except that the Gxy is at least 20 GPa" .
Chapter 6
Page 239: There is a missing term in the first equation of Example 6.2.2. The portion of the equation [(r2 -2r +1) (Xt2 Yt2 - Yt2 S2)]m2n2 should read [(r2 -2r +1) (Xt2 Yt2 - Yt2 S2) + 2rXt2S2]m2n2 . It is also possible to write this portion as, [(r2 +1) (Xt2 Yt2 - Yt2 S2) + 2r(Xt2S2 + Yt2S2 - Xt2Yt2)]m2n2 .
