Simulation Phantom aircraft collision on a concrete wall in Abaqus

In this tutorial, the Simulation Phantom aircraft collision with a concrete wall in Abaqus has been investigated. The concrete wall is modeled as a three-dimensional solid part. The Phantom is imported as an input geometry to Abaqus as a shell part. You can see a figure of the parts below

Since the September 11, 2001 attacks, the US Nuclear Regulatory Commission (NRC) has regulated large commercial aircraft in relation to safety assessments of nuclear power plants (NPPs) for beyond-design-basis events (BDBEs). For a design-specific assessment due to a large commercial aircraft impact on an NPP, a realistic analysis is required. A full-scale test is tremendously expensive to perform, and multiple tests increase the costs significantly. Therefore, a method known as a realistic numerical analysis is required to evaluate the time-dependent aircraft impact force, and the dynamic response of a target structure against this force

To model aircraft material, the Johnson-Cook hardening and damage are selected. The Johnson-Cook damage initiation criterion is a special case of the ductile damage criterion model for predicting the onset of damage due to nucleation, growth, and coalescence of voids in ductile metals. To model concrete behavior under the impact load, the Johnson-Holmquist material model is considered.

The dynamic explicit step with a general contact algorithm is used, and the proper boundary condition is assigned to the concrete wall. The initial velocity is applied to the aircraft also. The mesh should be fine to obtain the correct results

After the simulation stress, strain, damage for both parts, failure, force, and other results are available. You can see some figures for the results below
