Structural Analysis of Boraluminium Fatigue Damage

A structural model for estimating fatigue strength In composite materials (CM) is suggested in this paper. It is based on a structural theory of CM deformation and strength now being developed/1-4/ as well as on the results of numerous experimental studies on the fatigue strength of metallic CM (MCM) beams. To clarify this issue, following Is a brief description of i) the above-mentioned structural model of CM deformation and strength, li) testing technique and character of beam fatigue damage, ill) calculation of the stress-deformed state of beams while vibrating, according to the first bended mode with fixed vibration amplitude and iv) a structural model of fatigue strength evaluation.
