It is shown that the usual derivation of the equation for the deflection of thin beams that employs the well-known equation for the radius of curvature of a plane curve in known Cartesian coordinates is inconsistent with the assumption of an unstrained neutral axis. A derivation is presented ...
Furthermore we derive a general for- mula of aesthetic curves that describes the rela- tionship between their radiuses of curvature and lengths. 展开 被引量: 58 年份: 2005 收藏 引用 批量引用 报错 分享 全部来源 免费下载 求助全文 ResearchGate (全网免费下载) ResearchGate Citeseer Citeseer (全网...
The lens maker’s formula involves the focal length, refractive index of the material of the lens and the radius of curvature of the two surfaces of the lens. This formula is derived from the refraction of light on the two spherical surfaces of a lens. In Fig. refraction of light at the...
of this work, elastic FEM analyses of a bimaterial specimen with a center crack in the interface are carried out under tension; the two mode contributions of the CED can be evaluated on the basis of the corresponding domain integrals, independently of the radius of curvature at the crack tip...

It is known that the surface tension and the line tension depend on the radius of curvature of the liquid-vapor interface or the three-phase contact line. For nano-scale wetting phenomena, we should consider the curvature effects of the surface tension and the line tension. Thus, classical ...
The article concludes with the development of a "Worst-Case" Tipping Point Formula for use in determining when the Radius of Curvature in the Normal Section should be used in the elevation factor in the reduction of a LD.J. Elithorp

A previously employed anisotropic (quasi-) PML for conformal terminations is shown to be the large radius of curvature approximation of the anisotropic conformal PML derived herein. 1998 John Wiley & Sons, Inc. Microwave Opt Technol Lett 17: 231鈥 236, 1998....
