Energy absorption characteristics of sandwich panels due to foreign object damage


Chinmay Morajkar

Foreign object damage (FOD) usually happens when objects are sucked into jet engines powering military or civil aircraft. Under extreme conditions, FOD can lead to severe structural damage. More commonly it produces locally impacted sites of the fan and compressor airfoils, reducing fatigue life of these components. FOD is a prime cause for repair in aircraft engines. The present study deals with impact of projectile on solid and sandwich structures with different impact angles, the honeycomb core is generally used in between two face-sheet because of its advantage of weight reduction and high specific energy absorbing capability during impact. The modeling of the sandwich panel is done using HYPER MESH and the analysis is carried out using explicit solver LS DYNA 971 R 8.0 and finally a comparative analysis is carried out between solid and sandwich panel based on energy absorption and weight reduction of the structure.
