The stress analysis of micro-arc oxidation (MAO) coated aero Al alloys is the basis to reveal the mechanism of fatigue deterioration. To clarify effects of the coating defects on fatigue life. a stress calculation model with micropores and residual stress is established based on shear lag model in this study. The effects of porosity. https://thegreensjunglebeautyshops.shop/product-category/kids-leggins/
