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:

Tutorials for bird-strike simulation using ANSYS/LS-DYNA
Reza Hedayati,Mojtaba Sadighi +1 more
TL;DR: Considering a rigid target helps to better focus on the influence of the different parameters of bird models and contact algorithms, regardless of the response of the target structure, so bird strike against rigid target is investigated here only.

Finite Element Analysis on the Impact-Induced Damage of Composite Fan Blades Subjected to a Bird Strike
TL;DR: In this paper, the authors presented a numerical method to analyze the bird-strike impact as a soft-body impact on cantilevered composite panel, which enables predicting impact force on the panel appropriately, with laminate damage analysis to predict the impact-induced progressive damage in the composite.

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.
