• Page 222, Equation 5.40: The first term on the right-hand side should start with 2/J, not J/2 as written.
• Page 223, Equation 5.44: The second term on the right-hand side should contain \(\lambda^4\), not \( \lambda^2 \) as written.
• Page 224, Equation 5.55: Most of the time this equation is less useful than directly applying Equation 5.52.
• Page 225, on the middle of the page it says: “and \( \lambda = 2\)”, which should be “and \( \lambda = \sqrt{2}\)”.
• Page 225, Equation 5.58, the number 2 should be \( \sqrt{2} \).
• Page 253, Equation 5.113, the left-hand-side of the equation should be \( \mathcal{L}^{-1}(x)\).
• Page 253, Equation 5.114, the left-hand-side of the equation should be \( \mathcal{L}^{-1}(x)\).
• Page 263, Equation 5.125, the equation should be:
  \( \sigma_{planar} = \displaystyle\mu \left( \lambda^2 – \frac{1}{\lambda^2}\right) \frac{J_m}{J_m-(\lambda^2 + 1/\lambda^2 – 2)} \)
• Page 263, Equation 5.126, the equation should be:
  \( \sigma_{biax} = \displaystyle\mu \left( \lambda^2 – \frac{1}{\lambda^4}\right) \frac{J_m}{J_m-(2\lambda^2 + 1/\lambda^4 – 3)} \)
