Crack Analysis of Composite Beam Using Vibration Analysis Method: A Review

Composites are one of the popular materials because of their variable applications going from the aviation to the farming items. They very often experience vibration during functioning. Various examinations showed that presence of Crack in composite constructions is one of the significant reasons for disappointments in composite laminate designs. Recognizing deformities in constructions and its members is a significant perspective in deciding about their maintenance and complete substitution. Inability to identify the shortcomings has different outcomes, and at times may prompt a disastrous failure. The present research work revealed scientific and experimental examinations on the impacts of a crack on the cantilever bar with rectangular section. The goal of this review is to measure and to decide the degree of the damage magnitude and location of cracks. In analytical examination, finite element method (FEA) programming was utilized in designing the model. The outcomes showed that, by checking the difference in the natural recurrence (frequency) it is a simple and reasonable method to demonstrate the damage intensity and size. But for small crack depth, the natural frequencies are not a decent damage locator. Mode shapes showed great affectability to recognize the damage extent for every crack parameters. The aim of this paper is to review the literatures on the impact of vibration on composite structures exposed to various limit conditions.
