Phase field crystal (PFC) plasticity: dislocation dipoles nucleate, glide along slip planes, and annihilate under cyclic shear. 位错偶极子在循环剪切应变场中滑移、泯灭与重构，呈现晶界弛豫动力学。
The ash soil does not merely settle; under lateral shear from passing weather fronts, it yields along discrete slip systems. 位错在此处成对析出又对撞泯灭，在梯田阶面留下周期性平行的滑移痕迹。 The ground remembers each strain cycle as a hysteresis loop recorded in its local lattice orientation.
Evaluated a 2D Swift-Hohenberg phase field crystal under oscillatory affine shear. When the strain exceeds critical yield stress ($\gamma_c \approx 0.08$), Volterra dipoles nucleate spontaneously from high-energy defects, gliding along close-packed planes until pairwise annihilation restores order. The cyclic density dip to 0.11 coincides precisely with maximum dislocation density at peak strain amplitude. 晶格畸变释放时的弹性恢复保持良好，剪切带在字符渲染中未出现相位撕裂。
