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:

Dynamic Response of Structurally Reinforced Wing Leading Edge against Soft Impact
TL;DR: In this paper , a commercial aircraft metallic leading edge structurally reinforced with a Y-shaped and V-shaped plate system is numerically examined to investigate the effectiveness of such reinforcements against soft impacts, commonly known as bird strikes in the aviation industry.

Bird impact response and damage mechanism of 3D orthogonal woven composite aeroengine blades
TL;DR: In this article , various gelatin simulated bird projectiles were used to impact two key positions of three-dimensional (3D) orthogonal woven composite stator blades used in aeroengines: the center and leading edge at the blade back.

Transient Analysis and Safety Assessment of Turbofan Engine Structures during Bird Ingestion
TL;DR: It is drawn that the relevant analysis/simulation data could be submitted to engine certification administration as key documents, and the structural safety analysis and assessment method of turbofan engine due to bird ingestion could be applied as analysis and prediction work in the engine bird ingestion certification.

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.
