7 Virtual testing approach for sandwich panel joints
would require considerably more computational effort. At the same time, it is shown
that the implemented model is capable of predicting the strength and the damage progression of all three considered configurations with a single set of material and model
parameters, while the simulation time is between 1h-2h on a state of the art 4 core CPU
workstation depending on the panel thickness. Therefore, the model is considered to
fulfill the requirements and the top-level virtual test is considered verified.
