Detailed experimental observations have been made on the growth of individual fatigue cracks and on the evolution of cracks in off - axis layers in (0 / 90 /± 45)S and (± 45 / 90)S laminates. Three stages of fatigue crack growth in the laminates have been identified : initiation, steady - state crack growth (SSCG), crack interaction and saturation. The results show that SSCG rate is essentially constant under constant load, independent of crack length and crack spacing. Finite element models have been developed and used to calculate the strain energy release rates associated with the off - axis matrix cracking. A correlation has been achieved between fatigue crack growth rates in off - axis layers and the total strain energy release rates. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini!
