I am a PhD candidate in the School of Mechanical and Manufacturing Engineering, specializing in the field of composite structures. My research topic focuses on the analysis of composite overwrapped pressure vessels subjected to extreme cryogenic environments. My methodology involves both experimentations to characterize materials response and finite element modeling techniques to predict failure. I extensively use Ansys software to model the anticipated material damage modes due to the development of thermomechanical stresses within the global structure. With this work, adequate toughening techniques are introduced to suppress progressive damage, increasing the service lifetime of the tank.
