Two approaches are compared for estimating static fatigue lifetime at low cumulative failure probability. Both
ABSTRACT This paper reviews the dependence,of strength and fatigue of fused silica optical fiber on the
Request PDF | On Feb 22, 2018, Ephraim Suhir and others published Predicted static fatigue (delayed fracture) lifetime of a fiber
However, strength and static fatigue measurements of bulk glass specimens generally have too much scatter to provide a sensitive
Static fatigue is the phenomenon that describes subcritical flaw growth to such critical dimensions. Understanding the microscopic
Polymer-coated optical glass fibers subjected to static fatigue demonstrate a deterioration in resistance with time.
