摘要

提出了一种应变导向Kolmogorov-Arnold网络数字图像相关方法（SG-KAN-DIC）。SG-KAN-DIC用KAN取代了传统子集DIC算法中的形状函数，并用高精度的应变数据约束了KAN算法的复杂度，能够准确地表示感兴趣区域内的真实变形，有效地降低了系统随机误差。通过数值实验比较了不同噪声水平下不同复杂度的位移特性。结果表明，SG-KAN-DIC具有较小的分析误差和较好的抗噪声性能。通过四点弯曲试验验证了SG-KAN-DIC的可行性。

Strain-Guided Kolmogorov-Arnold networks digital image correlation method

A strain-guided Kolmogorov-Arnold networks digital image correlation method (SG-KAN-DIC) is presented. SG-KAN-DIC replaces the shape function in traditional subset DIC algorithm with KAN and constrains the complexity of KAN by high-precision strain data, which can accurately represent the real deformation within region of interest and effectively reduce the systematic random error. The numerical experiment is conducted to compare the displacement characterization of different complexity with different levels of noise. The results indicate that SG-KAN-DIC has smaller analytical errors and better anti-noise performance. The feasibility of SG-KAN-DIC is verified by a four-point bending test.
