1. Strength analysis of composite cables
Abstract Carbon Fiber Reinforced Polymer (CFRP) cables, due to their outstanding performance in terms of specific stiffness and strength, are usually found in civil construction applications and, more recently, in the Oil & Gas sector. However, experimental data and theoretical solutions for these cables are very limited. On the contrary, several theoretica

2. Numerical Simulation of Hot Closed Die Forging of a Low Carbon Steel Coupled with Microstructure Evolution
Hot closed die forging is a regular process applied to manufacture metallic components used in supporting and fixing cable conductors in electric power transmission lines. In this forming process, the final microstructure of the workpiece depends on the control of several processing parameters. In this study, simulation of the industrial forging process of a

3. Root temperature and energy consumption at different cable depths in electrically heated substrates
A finite element method-based model of a substrate heated by an electric heating cable buried in a thermal isolated container was experimentally validated with root mean square error values of root zone temperature ranging 0.25 to 0.62 ºC. The two-dimensional transient model allowed variations in the physical properties of the substrate with temperature, wa

4. Estudo do efeito do escorregamento dos cabos de borda em estruturas de membranas. / Sliding cables at the boundary of membrane structures.
Este trabalho apresenta a implementação computacional do elemento finito de cabo deslizando sem atrito, em ambiente MATLAB®, com a finalidade de modelar os cabos de borda não-aderentes das estruturas de membrana. Este novo elemento foi incluído no programa de análise de estruturas retesadas SATS, já previamente desenvolvido. Esta ferramenta é capaz d

5. Otimização de estruturas reticuladas planas com comportamento geometricamente não linear / Optimization of plane frame structures with behavior geometrically nonlinear
The aim of this work is to present a formulation and corresponding computational implementation for sizing optimization of plane frames and cable-stayed columns considering geometric non liner behavior. The structural analysis is based on the finite element method using the updated lagrangian approach for plane frame and cable elements, which are represented

6. Contribuição ao estudo das coberturas penseis
This work presents a finite element approach to static and dynamic analysis of counterstressed cable structures. Two nodes, constant strain finite elements are used to model hanging cables, plane prestressed cable trusses and 3-D prestressed cable networks. The two nodes elements are assembled with tniss, beam and frame elements to the static analysis or mix

7. Analise não linear geometrica de estruturas reticuladas com aplicação ao lançamento de oleodutos submarinos
A numerical scheme for the geometric non linear analysis of three dimensional cable and frames structures by the Finite Element Method is presented in this work. Two computer programs were implemented, one of them uses the modified and relaxed Newton-Raphson method and the other the Quasi-Newton Method for the solution of non linear system of equations. Simp
