Abstract
Composite materials find many applications in various fields of engineering, ranging from aerospace to civil constructions, automobile to marine engineering. The careful design of these materials demands great efforts to avoid catastrophic failure of these materials under real working conditions. The present study deals with the analysis of turbo-machinery blades made of composite material with pre-existed cracks. Blades are the key structural units in turbo machinery of the aeronautical and aerospace industries. The behavior of composite blades in turbo-machinery is depending on many parameters such as stacking sequence of composite laminate, and type of reinforcement using for the laminate. The effect of these design parameters on the structural behavior of composite blade is studied with the support of finite element method. Even with the careful consideration of above parameters, the composite blade performance deteriorates with the delamination. By knowing the performance of composite blades with preexisted cracks, the analyzer will get able to modify the design of the plate in existing working conditions. The aim of the present work is to explore the behavior of composite blade by varying types of reinforcement and laminate sequence with the preexisted crack using finite element method. The finite element (FE) models of composite blades with cracks are generated with ANSYS. The variation of normal, shear stresses is evaluated from finite element models. The FE models are validated with published results. The Present work is used for the effective design of turbo-machinery blades with preexisted cracks
