This research investigates composite overwrapped tank structures produced through filament winding and exposed to cryogenic loads. A 3D-FE Model, including parameters of the mandrel trajectory for designing the dome, junction, and cylindrical shell, is coupled with thermal degradation to replicate physical variations. Intralaminar damages, such as matrix cracking and fiber failures, are predicted using 3D Hashin criteria. The numerical analysis employs a multi-step technique, using Abaqus/Standard for a general static step in thermal simulation and Abaqus/Explicit for impact events on the pre-stressed composite tank. The presented numerical results include contact force, displacement, energy dissipation, and predicted matrix damage in each layer of the tank. The impact of temperature changes on the tank's response to impacts is explored, and a detailed examination of damage zones on the structure reveals that damages increased as the temperature decreased for all test samples.
