curvature angle has reduced the effect of debonding for the first
asymmetric mode, while it has increased this effect for the first
symmetric mode. The analyses for higher modes also show that the
effect of debonding may slightly be increased, decreased or remain
unchanged by the variation of curvature angle. Baba et al. (2011)
reported that the reductions in natural frequencies due to
debonding are greater for a curved beam. In this way, it can be
noticed that their conclusion is not general or is accompanied with
errors.
