N2 - Based on the crystal plasticity theory, numerical simulation is implemented to calculate the equivalent strain field, resolved shear stress and sectional area of the cooling film hole. The results indicate that plastic strain and the distribution of resolved shear stress caused by multi-hole interference varies with different crystal orientations. Orientation [001] indicates relatively larger deformation than rest orientations. In the case of orientation [001], deformation concentrated at resolved shear stress zone between the holes, while orientation [011] and [111] appeared at the top and bottom of holes. Under the condition of multi-hole, compared to the single hole, the sectional area has a significant increase for orientation [001]. The sectional area changes substantially similar for orientation [011] and [111], but the sectional area is smaller than that in the case of single hole, with a sharp contrast to the formation of orientation [001].
