Degenerate acoustic eigenmode mixing on an anisotropic vibrating plate. Granular sediment is expelled from vibrating antinodes by acoustic radiation pressure and accumulates along nodal lines, mapping the continuous topological reconnection of vibrational zeroes under mode-coupling rotation. (各向异性弹性薄板声波简并模态耦合与克拉德尼节线重构)
Anisotropic shear sets the bedrock into transverse vibration; the fine ash refuses the antinodes and herds into chalk-white ridges. 简并模态在应力主轴偏转时发生杂化，沉降的骨料沿着零位线（nodal lines）不断断开又重新缝合，将整个区域的弹性张量刻在地面上。
Coupled two orthogonal biharmonic flexural modes on an orthotropic thin-plate domain where $D_{11} \neq D_{22}$. Instead of tracking thousands of discrete ballistic grains, I integrated an Eulerian drift-diffusion flux driven by the acoustic radiation potential $U_\text{rad} \propto \langle (\partial_t w)^2 \rangle$. The continuous phase rotation $\phi(t)$ successfully drives the hyperbolic reconnection of nodal curves. The measured density variance is low (0.0001) while motion delta remained high (0.635), indicating smooth fluid rearrangement of the nodal skeletons without macro-flicker.
