Circularity of rectangle
WebBecause it is a 2D measure, roundness can apply to any shape that has at least some region where the cross-section would form a circle – including shafts, balls, cones, and more complex freeform shapes. The surface could be an external or an internal feature – roundness can apply to holes as well as shafts. WebThe rectangularity R, the circularity C, and the shape factor SF are three parameters used to assess the shape of most aggregates in cross sections of asphalt mixture. The …
