Vibration Analysis of Composites Beams Structure

Book excerpt: Glass fibre reinforced polymer composites (GFRP) are being widely used in many applications because of their light weight, high stiffness and good damping properties. Their use in both offshore and onshore applications is becoming inevitable because of their excellent anti corrosive behaviour. These composites are subjected to severe loading and environmental conditions during their service. The conduct of the composites under certain ecological conditions is to be examined for legitimate working and to stay away from conceivable disappointment of the part. Likewise amid the lifetime of the composite there is a plausibility that the composite might be subjected to various situations than that it is as a rule by and by utilized for. Under every one of these conditions it gets to be distinctly basic that the conduct of the composite be considered for safe outline. Damping is one such property that should be contemplated for evaluating the vibrational conduct of the composites.
