TLDR
In this article, the impact behavior of an artificial bird impinging a flexible aeroengine fan blade was analyzed using the LS-DYNA simulation model and the results showed that the initial contact area between the bird and target in the early phase of the impact event would have a significant effect on the peak impact force.About:

Bird impact — a growing threat for Aviation
TL;DR: In this article, the authors presented emerging hazards caused by birds and other small objects, which collide with fast moving aircraft in the air or on the runway, and examined issues associated with the high risk of accidents aligned with an increase in air traffic volume and bird acclimatisation to prevailing environments in the vicinity of airports.

An Enhanced Weighted Regression Model for Compressor Blisk Safety Analysis Regarding Dynamics and Uncertainty
TL;DR: It is validated that the EWRM is highly computational precision and efficiency in the dynamic reliability and sensitivity assessment of compressor blisk and the reliability probability and important degrees of influential factors can be regarded guiding the optimization design of compressor Blisk stress.

Structural Crashworthiness and Failure
Norman Jones,Tomasz Wierzbicki +1 more
TL;DR: In this article, failure in ductile material using finite element methods and modelling the process of failure in structures are discussed. But the authors focus on the inelastic rupture of ductile metal beams subjected to large dynamic loads, strain localisation and fracture in metal sheets and thin walled structures; impact on metal tubes; indentation and perforation; composite strength and energy adsorption as an aspect of structural crash resistance; crash response of composite structures; dynamic compression of cellular structures and materials; elastic effects in the dynamic plastic response of structure; impact performance of aluminium structures

Modelling of Bird Strike on an Aircraft Wing Leading Edge Made from Fibre Metal Laminates – Part 2: Modelling of Impact with SPH Bird Model
Michael A. McCarthy,J.R. Xiao,Conor T. McCarthy,A. Kamoulakos,J. Ramos,J. P. Gallard,V. Melito +6 more
TL;DR: In this article, a finite element model is developed for simulating the bird strike tests, using Smooth Particle Hydrodynamics (SPH) for modelling the bird and the material model developed in Part 1 of the paper for modeling the leading edge skin.
Impact Behavior of Low Strength Projectiles
TL;DR: An unsteady, hydrodynamic model of the impact of a low strength projectile on a rigid or semi-rigid target has been developed and impact tests of various materials including birds, gelatin, and RTV rubber have been conducted to validate this theory.

Modelling of impact forces and pressures in Lagrangian bird strike analyses
TL;DR: In this paper, a Lagrangian approach is adopted, interfacing the ESI/Pam-Crash solver code with an automatic trial-and-error procedure for the elimination of the excessively distorted elements.

The Development of a Substitute Bird Model
James S. Wilbeck,James L. Rand +1 more
TL;DR: A comprehensive program was conducted to develop a model synthetic bird for use in engine blade impact testing and it was determined that a projectile fabricated from commercial gelatin impregnated with phenolic mircoballoons most nearly duplicated the impact loading history of real birds.
