TLDR
Various methods of computer simulation that have been developed are presented in summary and bird strikes on a rotating spinner and an intake blade are investigated with the finite element program DYNA3D.Abstract:
External components of aeroengines, such as casings and intake blades, must be capable of withstanding bird strikes. Various methods of computer simulation that have been developed are presented in summary. Bird and component are divided into finite elements. The component model must allow for great elastic-plastic deformation, where the yield strength is a function of the strain rate. A model shape and a homogeneous substitute material must be defined for the complicated and nonhomogeneous structure of the bird. Bird strikes on a rotating spinner and an intake blade are investigated with the finite element program DYNA3Dread more

Competition in the air: birds versus aircraft
TL;DR: The first known aircraft fatality that was directly attributable to a bird occurred in 1912, when a gull (Larus sp.) was caught in the control cables of an aircraft, causing it to crash as mentioned in this paper.

A new bird model and the effect of bird geometry in impacts from various orientations
Reza Hedayati,Saeed Ziaei-Rad +1 more
TL;DR: In this paper, a bird model with geometry similar to a real bird (Bufflehead Duck) is introduced and compared to traditional bird models and also to experimental data. But, since all birds do not have the same body shapes and sizes, and since it is not always convenient to model a complex bird body, four substitute bird models are introduced.

Bird strike analysis on a typical helicopter windshield with different lay-ups
TL;DR: In this article, the effect of incident angle on the integrity of a typical helicopter windshield was investigated using smoothed particles hydrodynamic (SPH) finite element method and five types of lay-ups in a windshield (single layer stretch acrylic, single layer glass, two-wall cast acrylic, acrylic with Polyvinyl butyral (PVB) interlayer and glass with PVB interlayer) were considered and in each case the thickness which prevents the bird from perforating the windshield was calculated.
Validation of Available Approaches for Numerical Bird Strike Modeling Tools
TL;DR: In this article, the authors investigate the bird strike phenomenon in order to validate available numerical models through experimental tests and simulation tools and describe how to use the currently available test data while exerting caution as to their reliability.
