Optimizing the Shape of an Object to Facilitate Wrinkle and Stress Reduction

A method implemented by a computing system that facilitates formation of an object from a material comprises receiving an object model that specifies a top surface and a side surface connected to an edge of the top surface via a fillet that extends along the edge. At a particular region along the edge, adjacent planar regions of the side surface define an obtuse angle therebetween. The fillet is adjusted along the edge to have a first radius at a particular distance from the particular region and to have a second radius, smaller than the first radius, proximate the particular region. Output data associated with an adjusted model is communicated to equipment configured to form a mandrel that facilitates formation of the object. Adjusting the fillet to have a smaller radius proximate the particular region facilitates elimination of wrinkles in the material when draped over the mandrel to form the object.
