Improving composite cable performance: Nonlinear thermo-elastic analysis with temperature-dependent pretension and 3D cable elements

Abstract

Composite cables are widely used in various engineering applications due to their high strength-to-weight ratio and versatility. However, their performance is highly influenced by temperature changes and the application of pretension, which must be considered to perform accurate analysis. Fibrous materials, characterized by their high strength and flexibility, are incorporated into the cable structure to enhance its performance. This research paper presents a comprehensive study on the nonlinear analysis of cable structures made of fibrous materials considering temperature-dependent effects and pretension. A three-dimensional cable element model is employed to accurately capture the complex behavior of composite cables. The proposed approach allows for a more realistic representation of the cable's response, accounting for both mechanical and thermal effects. In order to effectively solve nonlinear equations, the Newton-Raphson (NR) method, a powerful iterative technique for solving nonlinear equations, is employed. This technique is employed to analyze the behavior of composite cables under various loading conditions, accounting for factors such as temperature dependence and pretension. Through extensive numerical simulations, the effects of temperature variation and pretension on the structural performance of composite cables are evaluated. The results provide valuable insights into the behavior of composite cables and offer guidelines for optimizing their performance in real-world applications. This research contributes to advancing composite cable design and engineering practices by considering the intricate interplay between temperature-dependent behavior, pretension, and nonlinear thermo-elastic analysis.
