Modelling Bird Impacts on an Aircraft Wing - Part 1: Material Modeling of the Fibre Metal Laminate Leading Edge Material With Continuum Damage Mechanics

Glass-based FML may be a suitable material for aircraft parts likely to be subjected to high velocity impacts from objects such as runway debris or birds. This article reports on a research study undertaken to examine the performance of a glass-based fiber metal laminates (FML) leading edge structure, and to develop analytical tools capable of predicting the structural response of such as structure to a bird strike. This article is the first in a two-part series reporting on this research. In this part, the authors describe the development of a material model for the FML, based on a recently implemented continuum damage mechanics (CDM) model and capturing its strain rate dependency. Results from the model are compared with experimental results on FML at variable strain rates and the model is shown to be capable of capturing most of the complex strain rate dependent behavior exhibited by these materials. The authors conclude that, considering the incomplete data available for the individual constituents of the FML (particularly the glass layers), the agreement between the simulations and experiments is very good. They note particularly the capturing of the complex failure process in the quasi-static 0 degree FML tests.
