Plane shock initiation sensitivity measurements for <110> single crystal pentaerythritol tetranitrate were extended to 20 GPa. The data of run distance versus input stress do not fall on the usual straight line on the Pop plot. From these data Arrhenius parameters were calculated. Computed activation energy was 6.4 kcal/mole, and the frequency factor was 5 x 10/sup 6//s. These are much lower than values obtained from isothermal heating experiments. These results can be used to support the idea that the uniaxial strain due to the shock leads to heterogeneous heating of the homogeneous material. 11 refs., 3 figs., 1 tab.
