Laminated Composites are increasingly being used currently in civil, aerospace, marine and other related weight-sensitive engineering relevance‘s requiring high stiffness-toweight and strength-to-weight ratios. Some of the structural components of, missile, aircrafts and ship structures can be idealized as composite plates and shell. This work is concerned with vibration (Modal) analysis of a laminated composite plate structure with different Angle
SS 301L (S30100), SS301 LN is the types of stainless steel which contains up to 8 % of Nickel , and 18 % of chromium. This is familiar and most useful member of stainless steel and a important factor in jet engines was the performance of the materials is very good for the disc of the engine. When we change the chemical composition within the certain limits according to ASTM standard different ranges of properties can be obtained for different application
