Simulation of destruction the engine with a bird strike in LS-DYNA. Short tutorial (incomplete)

Simulation the process of destruction of the engine blades and the engine casing in contact with bird Modeling is carried out in 2 stages: Stage 1: promotion of the motor rotor to the operating speed of rotation Stage 2: throwing bird on the blades of the engine Stage 1 is necessary to create the appropriate load on the motor rotor in working condition (during rotation). The rotor is the base and blades and spins from 0 to the operating speed of 80 revolutions per second. The obtained stress-strain state of the rotor is used in step 2. The model consists of a rotor transferred from the previous calculation, a bird and a casing. A bird with a speed of 250 m/sec is thrown on the rotating blades of the engine. Blade material - titanium, engine casing - aluminum. Determine the state of the rotor blades and the engine casing after the impact of bird at different time stages. The features of the process: the bird is modeled by SPH method; the prestressed state of the rotor is used; model of the destruction of the blades of the engine used the Gissmo model with parameters triaxiality and LODE parameter (model not shown). The video tutorial contains a video on the implementation of a full restart - conservation the stress state of the rotor and the transfer of this state to the stage of throwing the bird.
