Original abstract

A partial parametric study of FE simulations of bird strike tests of CFRP panel is presented. The simulation were performed with help of MSC.Dytran and MSC.Nastran software, where two different simulation methods were used: Lagrangian-Eulerian (LE) and Smooth Particles Hydrodynamics (SPH). During the study the simulation results were compared to test ones. In particular the maximum deflection profile and failure extent and position were compared. The main objective of the study was to find both the parameters of FE models, which significantly influence the simulation results, and choose the software and simulation method, which give the best correlation with experiment. Based on correlation of panel maximum deflection and failure extent and position conclusions about influence of the investigated parameters on simulation results and about advantages and disadvantages of different simulation software and methods are made.
