Fatigue failure often shows up towards the end of life in the backup roll (BUR) in belt fusing, as shown in Figure 1.This paper has two objectives: (1) To develop a model or description of what drives fatigue in an elastomer from material and loading perspectives,
that can be applied in fusing irrespective of the particular application at hand; and (2) to use this capability to examine fatigue, clarify the reason for the catastrophic failure in printers, and identify directions to meet the spec on life, as well as assess the impact this might have on
other fusing attributes. <fig position="float" id="s92_f.1"> <label>Figure 1</label> <caption>BUR Failures in the Rubber Layer or Primer / Core Interface at the End of the Roll </caption> <graphic mime-subtype="tif" xlink:href="Images\s92_f01.tif"
