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:

On the difference of pressure readings from the numerical, experimental and theoretical results in different bird strike studies
TL;DR: In this paper, two finite element bird models (hemispherical-ended cylinder and mallard) are used and two ways of pressure reading (averaging and sensor) were used to find out where these differences between the experimental, theoretical and numerical values come from and that what the true values are.

Deterministic solutions for contact force generated by impact of windborne debris
TL;DR: In this article, the impact action has been quantified and the predicted impact force can be applied to the target in a quasi-static manner for predicting damage, which can be verified by comparison with experimental results across a wide range of impact scenarios.

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

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.

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.
