Finite element study of behavior and interface force conditions of seven-wire strand under axial and lateral loading
Highlights Constrain in strand is partial restrained but close to fixed end. Strand shows elastic–plastic performance as the increasing level of stretching. Friction has little influence on longitudinal stiffness and limited influence on lateral behavior. Microslip and contact line migration mainly occurred between helical wires. Both strand bending phase and wire bending phase were observed near the termination when bending.
Abstract Although numerous FE models have been proposed to analyze the mechanical behavior of simple strands, they seldom examine the contact condition and lateral loading behavior that may influence local stress distribution and lifetime performance. In this study, serial 3D FE models of a seven-wire strand were developed to discover the interface mechanism under longitudinal and lateral loading. A partially restrained model was proposed and carefully studied. Friction minimally influenced longitudinal stiffness and had a limited effect on lateral behavior. FEM analysis predicted uneven stress distribution under lateral loading simulation. Both strand bending phase and wire bending phase were observed near the termination. Microslip and contact line migration mainly occurred between helical wires.
