    The drop-in value of HDPE creep modulus over time under different compressive stress levels at room temperature is illustrated in Figure 5. The trend of creep modulus curve is similar to the creep strain curve, but in the inverse direction, where the material loses a substantial amount of creep modulus initially followed by a gradual saturation over time.

    The results show that Yield stress increase with temperature by (15.4%) for HDPE and the temperature has no effect on yield stresses of PVC. The modulus of elasticity varied in each temperature for both materials selected and the maximum shear strength, however, showed a slight increase in this temperature range by (1.4%) for HDPE but slightly decrease by (2%) for PVC.
