WebAug 3, 2024 · The dynamic shear modulus and damping ratios of fine fused quartz (0.5–1.0 mm, 0.1–1.0 mm) through resonant column tests (RCT) and cyclic torsional shear tests (TST) were briefly introduced [ 6, 7 ]. The cyclic undrained behavior and liquefaction resistance of fine fused quartz was also studied by Kong et al. [ 8 ]. WebFused quartz is an extraordinary material for numerous industrial applications. The single-component glass consists solely of silica (SiO2). Through its unique combination of thermal, mechanical and optical …
