The HITF has created a 3D finite element model
of the ISS which categorizes each different shield
configuration used on the outer surfaces of the spacecraft. The model serves as
input to the overall threat assessment. The shield properties contained in the model include thickness, material density, and
spacing. The model is shown with radiators, solar arrays and
trusses in place. The solar array & radiator elements are typically
left out of risk assessments, while the trusses are left in for shadowing
purposes (the trusses stand in the way of other more critical elements from being struck).
