RAMA KANDULA, P. S. PRASAD, DINESH KUMAR HARURSAMPATH

Abstract


Thick composite panels with sandwich construction are employed in a wide range of structural applications in the aerospace industry. For example, sections of honeycomb sandwich panels often exceed 50 mm in fan containment cases of commercial jet engines. Impact is the typical design load for the thick composites in this case. During the ballistic impact, energy transfer takes place from the projectile to the target, through a combination of deformation as well as damage initiation & progression. Delamination is one of the major damage & energy absorbing mechanisms.
