“…Although the level of load at which the micro-damaging process is commenced, depends on many factors and cannot be reasonably generalized. According to Paipetis and Aggelis (2012), a clear growth of micro-damage areas is observed when the value of loads equals to approximately 0.75 of breaking load. The discrepancies between the characteristic of response of individual components of laminate may lead to the occurrence of damages on the metal–composite interface.…”

Purpose The purpose of this study is to investigate the results of reinforcing fibre metal laminates with glass fibres under low-cycle fatigue conditions in a limited number of cycles. Design/methodology/approach The tests were carried out on open-hole rectangular specimens loaded in tension-tension at high load ranges of 80 and 85 per cent of maximum force determined in static test, correspondingly. The number of cycles for destruction has been determined experimentally. Findings By means of microscopic observations, it was possible to determine the moment of crack initiation and their growth rate. Furthermore, it was possible to identify the impact of reinforcing fibre orientation in composite layers, material creating the metal layers, on fatigue life and on nature of crack propagation. Practical implications This work validates the possibility of increasing the resistance of fibre metal laminates to low-cycle fatigue by modifying the structure of the laminate. Originality/value The resistance of fibre metal laminates on low-cycle fatigue is not widely described and the phenomena occurring during degradation are poorly understood.
