For example , Beardmore and Rabinowitz ( 23 ] have noted that softening ( i . e . ,
a lowering of the yield strength ) under cyclic loading at a constant strain range is
characteristic of unnotched glassy linear polymers ( see Section 2 . 5 ) ; this ...

It was noted , however , that a relatively larger beneficial effect of stabilizer
addition on fatigue behavior was found in stress - controlled tests than in the
strain - controlled ones . As discussed above , this was due to the fact that a
smaller strain ...
