Instantaneous radius of curvature
The radius of the curvature of the stressed structure is related to stress tensor in the structure, and can be described by modified Stoney formula. The topography of the stressed structure including radii of curvature can be measured using optical scanner methods. Se mer In differential geometry, the radius of curvature (Rc), R, is the reciprocal of the curvature. For a curve, it equals the radius of the circular arc which best approximates the curve at that point. For surfaces, the radius of curvature is … Se mer In 2D If the curve is given in Cartesian coordinates as y(x), i.e., as the graph of a function, then the radius of curvature is (assuming the curve … Se mer • For the use in differential geometry, see Cesàro equation. • For the radius of curvature of the earth (approximated by an oblate ellipsoid); see also: arc measurement • Radius of curvature is also used in a three part equation for bending of Se mer • do Carmo, Manfredo (1976). Differential Geometry of Curves and Surfaces. ISBN 0-13-212589-7. Se mer In the case of a space curve, the radius of curvature is the length of the curvature vector.

NettetIn mathematics, curvature is any of several strongly related concepts in geometry.Intuitively, the curvature is the amount by which a curve deviates from being a straight line, or a surface deviates from being a plane.. For curves, the canonical example is that of a circle, which has a curvature equal to the reciprocal of its radius.Smaller … NettetThe tangential radius of curvature ( rt r t) in the tangential section, also known as the instantaneous radius of curvature refers to the distance, PCt PC t. The tangential curvature is referred to as axis independent, because the center of curvature does not have to lie on the optical axis. 13–15 Fig. 2 Download
