Abstract: Composite materials are increasingly used in aerospace, naval and high performance civil engineering structures high-strength-to weight, stiffness-to-weight ratio, corrosion resistance, and longer fatigue life and stealth characteristics. Structural elements subjected to in-plane periodic forces may lead to parametric resonance due to certain combinations of the values of load parameters. The instability may occur below the critical load of the structure under compressive loads over wide ranges of excitation frequencies. Several means of combating resonance such as damping and vibration isolation may be inadequate and sometimes dangerous with reverse results. The present work deals with the study of the parametric instability characteristics of delaminated cross ply composite plates subjected to periodic in-plane load. A first order shear deformation theory based on finite element model is developed for studying the instability region of mid plane delaminated composite plate.The bo...
