Development of an effective modeling method for the local mechanical analysis of submarine power cables
The structural complexity of submarine power cables (SPCs) and complex contact issues within present significant challenges in their local mechanical analysis. This research introduces an advanced modeling method developed for analyzing the mechanical behavior of SPCs under a range of different loadings, emphasizing both accuracy and efficiency. The method’s accuracy is validated through a comparison of simulation results with tests conducted on three-core SPC and single-core samples. Efficiency is demonstrated by the superior calculation speed of our model relative to traditional full-scale models. This improved performance is achieved by adopting periodic boundary conditions derived from the homogenization method applied to slender beam-like structures, and by employing a specialized combination of elements to model the helical metal components within the SPCs. The resulting model provides robust capabilities for the mechanical analysis of SPCs. I have made the codes in this research open access. Please find them in Codes page.

Development of an analytical and a numerical model for the fracture analysis of fiberglass reinforced flexible pipes
Composite structures, such as the fiberglass reinforced structure studied in this project, have been normally treated in previous research as homogeneous anisotropic laminated plates regarding the investigation of their mechanical properties. Throughout this research, this specific structure is considered in a different way in which the fiberglass and polyethylene matrix are treated separately. By using the proposed method, the material plasticity of polyethylene and the fracture stress of the fiberglass can be taken into account, and thus the fracture of the fiberglass inside the fiberglass reinforced flexible pipes(FGRFP) can be predicted. The mechanical behavior of FGRFP under two main real-life loadings(tension and internal pressure) is investigated by using analytical and numerical methods based on the proposed technique. Experiments are used to verify the results.
