Abstract
In this paper, the free vibration analysis of simply supported bimodular composite material laminated curved beam has been carried out using equivalent stiffness method. The Non-dimensional free vibration frequencies for positive half of vibration cycle and for negative half of vibration cycle have been presented for different ratio and laminated scheme. The analysis is based on classical beam theory. It is observed that the percentage difference of free vibration frequencies obtained from different equivalent stiffness method is more for angle ply laminated beam and for cross ply laminated beam the percentage difference is very less.
