Title of the PhD Project: Deployable Cable Nets for the Active Removal of Space Debris

Supervisor(s): Prof. Paolo Sebastiano Valvo, Prof. Angelo Pasini

Abstract of the PhD project:

Deployable cable nets are promising capture systems for the active removal of space debris. Modelling and analysis of their deployment, capture, and post-capture phases are crucial for the effective design of an operative mission. The candidate developed a finite element model of the cable net with lumped nodal masses and cable elements. The nodal positions have been assumed in the model as the main unknowns of the problem. Large displacements and finite deformations have been considered through the Green-Lagrange strain tensor. Cable elements have been assumed to react only in tension according to a hyper-elastic constitutive law. Global damping has been considered according to Rayleigh's hypothesis. The governing equations has been solved numerically at first by means of the Runge-Kutta method with variable time step, and later by means of the Newmark method to overcome some issues related to the rapidly changing phenomena. The contact phenomena arising after the impact with the target have been treated only on a theoretical point of view. As an illustrative example, the simulation of the three-dimensional deployment of a planar, square-mesh net is considered.
