In any case , crazing must play a major role in determining the strength of a
polymer under either static or fatigue loading . ... to bear load ; crazing may well
constitute the ultimate limitation to static strength in a homogeneous glassy
polymer .

Crazing and Shear in Fatigue Although little detailed information is available , it
seems likely that some combination of crazing and shear response exists during
fatigue as well as in static tests . As shown in Fig . 4 . 28 , clear evidence exists for
...

Assuming that the rate of strength decrease over time was inversely proportional
to some power of the residual strength , and taking into account the distribution of
static strengths , they derived an expression for the fatigue life distribution .
