Poster 20: Michael Blum – Numerical Investigation of the Coupling Effect of Pore Shape and Fracture Orientation on the Mechanical Properties of Amorphous Silica

Faculty mentor: Pania Newell

I investigated the effect of pore shape and pre-existing fracture orientation on the mechanical properties of amorphous silica. I simulated silica under load at the nano-scale with three pore shapes and three fracture angles and measured different properties, including Young’s Modulus and max stress. Due to where the silica cracks, I conclude that there is a coupling effect occurring; however, more research is needed to understand the underlying mechanisms, such as bond breakage patterns.
