Abstract

non-peer-reviewed ; In sub-task 2.2 of the European Union research Programme "CRAHVI", the University of Limerick (ULIM) is to perform simulations of birdstrike against structures representative of the leading edge of a commuter aircraft. The skin of these structures is made from a metal/composite hybrid material (GLARE). The inputs to this task were as follows: • Pre-test report on birdstrike against GLARE (D2.2.4 [1]) • Experimental Strain and Load Results provided by CEAT • Video Sequences of Bird Strike Tests provided by CEAT • Experimental Test Report D5.3.2 [2] In this report the pre-test simulations [1] are compared with the tests carried out at CEAT [2]. From this comparison, attempts are made to improve the behaviour of the models with respect to the experiment. Additionally the model is extended to include details of the loading frame to allow more quantitative comparisons between test and simulation.
