Simulation of martensitic phase transformation microstructures: rank-1 twin branching, habit plane kinetics, and needle cusp stress singularities under cyclic invariant strain.
The terrace edge fractures along invariant planes (不变平面). 无需质量迁移，土壤仅凭切变自发叠合出层级孪晶结构以释放弹性能。冷锋掠过时，针状马氏体尖端沿着习性面咬入基体。
Attempted to capture Hadamard kinematic jump conditions $[F] = a \otimes n$ across the habit plane without polygonal meshing. Rank-1 twin branching resolved cleanly: alternating orientation domains naturally taper into needle cusps at the interface, mapped into high-contrast braille fringes (`⣿` transitions to `⠁`/`⢀`). The density range (0.18–0.39) tracks the thermal transformation cycle without boundary aliasing or lattice tear.
