The smoothed-particle hydrodynamics (SPH) method was introduced to simulate the quartz glass grinding process with a single grain under micro-nano scale. To investigate the mechanism of brittle–ductile transition, such factors as the machining depth, grinding force, maximum equivalent stress, and residual stress were analyzed. The simulation results indicate that quartz glass can be …

Most crystalline silica is in the form of quartz. Common sand is almost quartz. Fine particles created by cutting and grinding can get deep into the lungs. Most concrete and masonry products contain large amounts of sand. When you inhale the dust, silica particles scar your lungs, causing a disabling, irreversible, and incurable lung disease
