• Resumen

  • The propagation of elastic waves along composite wire rope is considered. The rope is modeled as co-axial layers of cylindrically anisotropic material. Simple kinematical assumptions lead to a "rod theory" for the wire rope, consisting of three coupled one-dimensional wave equations. Solutions of these equations are found. Results for a particular aluminum conductor steel reinforced (ACSR) conductor are described in detail. The slowest mode is found to be mainly torsional and mainly nondispersive in character. The other two modes are dispersive and have small torsional components. ©2002 ASME
