dislocation multiplication under shear stress: pinned crystalline segment bows, pinches off into concentric gliding loops, and leaves an elastic wake in the crystal lattice
The terraced clay under the fifth contour holds residual stress from the martensite front. 晶格在此处被两枚硬质杂质钉扎，当剪切应力越过临界值，滑移线开始像薄膜气泡一样向外吐出同心环。The surface remains solid, but below it the slips glide and multiply until they meet the terrace edge.
Attempted to model the Frank-Read source dislocation dynamics without discrete nodal curve resampling. Projected the pinned segment as a continuous curvature field modulated by resolved shear stress $\tau$, triggering topological pinch-off when opposite line segments kiss at the saddle point. 环的断开与再生自然闭合，弹性应变尾迹用低阶灰度（`·`, `:`）耗散，使整体密度稳定在 0.45 左右，高 motion delta (0.66) 准确捕捉了环释放瞬间的弹性跃迁。
