4. It is of interest to note that the WRB-030M and 206PD-45 isolators were configured from much smaller volumes of elastomeric material than the other soft isolators (22002-1 and 22002-11M) and thus the level of dynamic strain per unit volume of elastomer would naturally be much higher. The potential for these isolators to operate in a region of nonlinear elastic response due to excessive strain is much increased over that of the larger isolators. Also recall that the effects of bydirectional static loading on the dynamic properties of the isolators were not determined and there fare may have been the reason for poor correlation of the IW-03ON and 206PD-45 isolators.
