Abstract: This study aims to validate the effectiveness of DIC (Digital Image Correlation) for evaluating the bending strength of gear teeth for rotary-wing aircraft though static and fatigue tests.Since the application of conventional strain gauges is limited for small size gear teeth, a non-contact full-field strain measurement technique based on DIC was employed.The experiments were conducted using a universal testing machine, and the strain distributions measured by DIC were compared with FEM (Finite Element Method) result.The experimental results showed a high correlation with the numerical predictions, demonstrating the applicability and reliability of the DIC technique for gear tooth bending strength evaluation.초 록 본 연구는 회전익 항공기용 기어 치를 대상으로 정적 및 피로시험을 수행하고, 기어 치 굽힘강도 평가에서 DIC(Digital Image Correlation) 기법의 유효성을 검증하는데 목적이 있다.기존의 Strain Gauge는 기어 치 형상이 작은 경우 적용에 한계가 있어,
