Numerical Analysis of a Spacecraft Protection Systems

Phase 1: Capability towards developing a numerical simulations approach. Specific technical objectives include: - Literature review on existing capabilities catastrophic collision threshold analysis, including numerical and empirical models / approaches. - Development of a range of low fidelity models; - Validation of the model against the high-fidelity models; - Specify the minimum level of modelling details required to obtain predictive results; - Determine size effects in the context of material vs structural response, including the strength change, as function of impactor size; - Determine the stress distribution within the structure and propose recommendations to guide development of appropriate failure criteria; - Through simulation, identify catastrophic impact specific energies as a function of projectile size; - Provide an assessment of the mass and trajectory of any fragments that may be generated during the impact cases of interest to UKSA; - Compare results against NASA Standard Satellite Breakup Model (SSBM) to better understand the influence of debris cloud formation and properties, resulting from collisions with limited information, to guide design recommendations to improve predictions of future collisions. for the breakup of a complete satellite to help define Catastrophic Collision Threshold.
