Step into the world of explicit dynamic modeling as we explore into the captivating scenario of an F-4 Phantom crashing into both a concrete and rigid wall. Through this model, you will gain invaluable insights into the construction of an explicit dynamic model using aluminum alloy, a material commonly used in aircraft structures.
To accurately capture the impact scenario, our model incorporates nonlinear and strain rate-dependent effects, necessitating the utilization of Johns-Cook's constitutive law for metal plasticity. Additionally, the Concrete Damage Plasticity model is employed to accurately represent the behaviour of concrete.
To facilitate a comprehensive comparison of impact phenomena, it was conducted simulations of the aircraft colliding with both a rigid wall and a concrete wall. For the rigid wall simulation, a rigid body with identical height and width dimensions as the concrete wall is employed. The wall is fixed in all degrees of freedom at its reference point.
To optimize computational efficiency, the aircraft is positioned in front of the wall with an initial velocity of 800 km/h in the flight direction. This approach allows us to efficiently analyze and evaluate the results of different impact scenarios while reducing overall computational time.
