EFFECT OF CYCLE PROFILE ON THE BIAXIAL COMPRESSIVE FATIGUE PERFORMANCE OF FILAMENT WOUND LAMINATES.
Abstract
The results of a program to study the effect of cycle profile on the biaxial compressive fatigue performance of glass reinforced plastics are presented. A description of the materials used, and methods of specimen fabrication and preparation is included. The results of specimen characterization as well as the techniques employed for ultrasonic inspection of the finished specimens are discussed. The results of biaxial compressive fatigue experiments, aimed at (1) establishing the effect of cycle profile, and (2) studying fatigue effects at low stress levels, are presented and discussed. Some observations of fatigue damage sites in unfailed specimens by macroscopic inspection of specimen cross sections is included. A literature review of the effect of frequency on the fatigue strength of metallic materials is presented in an appendix. An analysis of the ultrasonic inspection records obtained during the course of the study is also included as an appendix. (Author)
