摘要：
Fatigue behavior of quasi-isotropic carbon/epoxy laminates were studied, using six stacking sequences. Experimental results show that there is a significant stacking sequence effect on monotonic and cyclic performance of laminates. Though by changing the stacking sequence the difference between failure strength of the strongest and Weakest lay-ups reaches only to similar to 12 %, the difference between fatigue lives (cycles to failure) increased similar to 1000% in some loading regions. In addition, both linear and sigmoidal functions were examined to model the fatigue life behavior. (C) 2011 Published by Elsevier Ltd. Selection and/or peer-review under responsibility of ICM11
