An abrasive-wear model for undersea lightguide cable

An abrasive wear model for a cable, developed from the theory of material wear, is presented. This model is a modification of a model previously proposed by the author. The model is more accurate and general because it incorporates the frictional coefficient as a variable. The present model reduces to the former model when the frictional coefficient is set to 1. The present model was applied to an undersea lightguide cable and was able to account for differences in cable structure, materials, geometry, frictional coefficient, loading, and velocity. It is useful as a design guide for estimating the maximum permissible velocity and/or suspension length
