... and subjected to chemical analysis and low-cycle fatigue tests. Based on their findings, investigators concluded that the bolts failed due to fatigue compounded by excessive clearances and poor surface finishes. The chapter provides a number of recommendations addressing these issues and related concerns...

An important concern in the testing of polymers is that the attributes of the fatigue test are crucial to the relative ranking of fatigue...

... components. Thus, R = 0 was an advantageous baseline for axial force-controlled testing in the nominally elastic, high-cycle fatigue regime. This advantage, however, was soon lost once low-cycle fatigue testing came into its own with the development of reliable extensometers, closed-loop servocontrol...
