About Paper:

Quartz particles moving at high velocities undergo complex stress states during impact while causing damage, which is pivotal to understand for aircraft engine blade design. During impact, quartz particles undergo fracturing and amorphization, making it very difficult to collect the particles after impact and learn about the impact's effect. To facilitate a greater understanding for quartz particles after collisions, this research aims to design a particle catchment chamber for quartz after impacting a target substrate for post-mortem analysis. The initial portion of this research determined the specifications for a quartz collection chamber and its design. The shape of the collection chamber depends upon the restitution coefficients of quartz and the probabilities of particle fracture at different impact velocities. Considering the high fracture rates and low restitution coefficients for quartz, the most effective chamber types are short in length and minimize sharp corners. A single-stage light-gas particle gun was used to fire quartz particles at an aluminum substrate. Prototype catchment chambers will be tested for their ability to contain post-impact quartz particles. These tests will determine any necessary modifications to the catchment chambers. This research evaluates the properties of a suitable collection chamber for quartz particles after impact. Further work involves determining the dynamic fracture behavior of quartz during ballistic impact. Keywords: [no keywords provided]
