title = "Effect of convex platform on stress distribution in nickel-based superalloy plate produced by Vacuum Countergravity Casting",
abstract = "The effect of convex platform shape on stress distribution in nickel-based superalloy thin plate produced by Vacuum Countergravity Casting (VCC) has been studied by numerical simulation. The result shows that convex platform significantly changes the stress distribution in its adjacent area. The stress-affected zone (SAZ) of both types of convex platform appears uneven. SAZ is significantly greater in the diagonal direction than that in the horizontal direction. The angle effect contribution rate (AECR) is defined. When S1=1mm and S=6, AECR has the larger values in both convex platform shapes, and AECR of square convex platform is even up to 7.589. When S1 is larger than 2mm, the relationship between angle effect and S1 or S is not obvious for square convex platform.",
