Multimaterial bird model for bird impact simulation using SPH method

Abstract

Bird strike case is a part of the passenger aircraft certification requirements.The numerical calculation of bird crash cases can ease the burden and time of testing to be performed.The definition of a valid bird model is often a problem in modeling bird impact cases.One of the modeling approaches that can be used is the smooth particle hydrodynamic method. In this method, birds are modeled as fluid particles that have a certain number of parameters.There are a number of geometry variations and bird model parameters that can be used, including physical properties of fluids, materials, and various other controls.The paper focuses on the building the multimaterial bird model that is more representative than tradtional bird model, but simple to make.
