Oxide Glasses have many industrial applications. However, they are brittle ! It is well-known that oxide glasses undergo sudden catastrophic fracture (e.g. glass crashing to the floor). Still, there is another fracture mode less noticeable where crack fronts speed ranges from sub nm/s up to mm/s. The growth of these crack fronts is aided by environmental parameters including atmospheric humidity and temperature, and the crack front velocity depends on the local stress felt by a crack tip, coined the stress intensity factor (K). Currently, our experimental setup permits imaging the time evolution of the crack front and post-analysis provides the crack front velocity. Additionally, finite element simulations give way to an indirect measurement of K. In recent years, digital image correlation (DIC) techniques have proven to be a powerful tool to determine K. It works well for soft materials and/or large samples that exhibit significant deformation under loading. However, it is more challenging for stiffer materials and/or smaller samples of interest in the project. Recently, our team developed a new protocol to capture the displacement field around a crack front in oxide glasses. Initial results are promising, yet the experimental protocols remain to be optimized and qualified. This is the goal of the proposed internship. The selected intern will gain expertise in various fields: pattern deposition, experimental mechanics, DIC image analysis, etc.
