A REVIEW ON STUDY OF COMPOSITE MATERIALS IN PRESENCE OF CRACKS

Abstract

Composites materials are commonly used in automobiles, aircraft structures etc. due to their high specific strength and stiffness. Composites ability to retain functionality in the presence of damage is a crucial, safety and economic issue. The fatigue failure mechanisms have been widely studied. Matrix cracks, fiber break, dis-bonding and de-laminations are the main causes for progressive failure of composites under fatigue loads. In this paper, detailed review on composite in presence of cracks under different types of failure mechanisms etc have been discussed.
