The form of this relationship is given in Equation 2, the bulk stress model. Equation 8 gives the linear form of the bulk stress model used for regression analysis. 81 (8) The predicted resilient moduli obtained from the bulk stress model gave a poor correlation to actual resilient moduli (Figure 2).
