    We computationally investigate the compression-induced reversible stripe rearrangement process, which is experimentally observed for the spontaneously formed pattern of microwrinkles on a Pt-sputtered elastomer surface. We propose a rough model for the wrinkles in a small bending regime considering the pattern memory of the neutral state with the strength parameter s, which should be attributable to the degree of material flow during initial pattern formation. The original pattern recovers after a compressive perturbation within finite time periods above the specific value of s. The simulated stripe rearrangement process shows qualitative agreement with the experimental results. In particular, the hysteretic behavior is reproduced and discussed in relation to s.
