The geodesic curvature and torsion of an elastic curve are evaluated if they exist as the solutions of the differential equations for all different cases. Due to elastic curve definition, the minimum principle theorem is applied to elastic energy function which is defined as the integral of the squared geodesic curvature of the curve.]]>Love, A.E.H.,19274th Edn.,Pages: 643Pages: 643Hsu, M.H.,20077119Yanti, P.A.A. and T.M.
