Simulatio bird strike impact with SPH method to the composite blade in Abaqus

In this tutorial the Simulatio bird strike impact with SPH method to the composite blade in Abaqus has been investigated. The bird is modeled as the three-dimension solid part. The composite blade with eight layers is modeled as three-dimensional shell part. You can see a figure of the assembled parts below

A bird strike is strictly defined as a collision between a bird and an aircraft which is in flight or on a take off or landing roll. Bird Strike is common and can be a significant threat to aircraft safety. For smaller aircraft, significant damage may be caused to the aircraft structure and all aircraft, especially jet-engined ones, are vulnerable to the loss of thrust which can follow the ingestion of birds into engine air intakes. This has resulted in a number of fatal accidents.Bird strikes may occur during any phase of flight but are most likely during the take-off, initial climb, approach and landing phases due to the greater numbers of birds in flight at lower levels. Since most birds fly mainly during the day, most bird srikes occur in daylight hours as well. The nature of aircraft damage from bird strikes, which is significant enough to create a high risk to continued safe flight, differs according to the size of aircraft. Small, propeller-driven aircraft are most likely to experience the hazardous effects of strikes as structural damage, such as the penetration of flight deck windscreens or damage to control surfaces or the empennage. Larger jet-engined aircraft are most likely to experience the hazardous effects of strikes as the consequences of engine ingestion

To define the bird behaviour Us-Up equation of state is used. To model composite under impact load, lamina elastic model with Hashin damage criterion is selected. The dynamic explicit step with a general contact algorithm to consider all contact in the contact dommain is considered. The initial velocity is assigned to the bird, and voundary condition to the blade. The mesh should be fine to get proper results
