AFM과 유한요소법을 이용한 터빈 블레이드의 파손해석에 관한 연구
A Study on Failure Analysis of Turbine Blade using AFM and FEM
초록
Turbine blade has trouble of cracking at root region. Fracture surface of blade root is surveyed by SEM and AFM to clear relation between fracture mechanical parameter and surface parameter (striation width and surface roughness). Service stress is predicted by maximum height roughness
