Cylindrical Coordinate System an overview | ScienceDirect Topics
A cylindrical coordinate system, as shown in Figure, is used for the analytical coordinate axis r, θ, and z denote the radial, circumferential, and axial directions of RTP pipe, respectively. The local material coordinate system of the reinforced tape layers is designated as (L, T, r), where L is the wound direction, T is the direction perpendicular to the aramid wire in ...
