Key Responsibilities
Perform explicit dynamic bird-strike analysis using Altair Radioss for aircraft structural components and assemblies.
Conduct structural integrity assessments of primary and secondary aircraft structures subjected to bird impact and other high-rate energetic loading.
Develop and execute detailed nonlinear finite element models including:
CFRP composite structures
Metallic airframe structures
Polycarbonate transparencies and windshields
Hybrid composite/metallic assemblies
Fasteners, joints and relevant interfaces
Define appropriate material models, failure criteria, contact definitions, boundary conditions and impact scenarios for bird-strike simulations.
Model bird impact using suitable bird material/constitutive representations, including appropriate SPH or equivalent approaches where applicable.
Perform composite damage and failure assessment, including relevant intralaminar and interlaminar failure mechanisms.
Evaluate structural response including:
Global deformation
Local damage and penetration
Material failure
Delamination
Cracking/fracture




Energy absorption
Residual structural integrity
Assess polycarbonate transparency/windshield response, including deformation, cracking, penetration and containment behaviour under impact.
Perform model setup, mesh sensitivity studies, correlation and verification activities to establish confidence in simulation results.
Post-process and interpret large volumes of explicit dynamic simulation data and identify critical failure modes.
Correlate simulation results with test data and/or physical bird-strike test results where available.
Prepare detailed engineering reports documenting assumptions, methodology, model validation, results, failure mechanisms and conclusions.
Support design substantiation and certification activities through technically robust analysis and engineering justification.
Work closely with structural design, materials & processes, testing and certification teams to develop practical so
