Background
Greta Ongaro is an aerospace engineer and a PhD Student in Space Sciences, Technologies and Measurements at the Center of Studies and Activities for Space “G. Colombo” (CISAS) of Padova (Italy). She graduated in Aerospace Engineering at the University of Padova with a master thesis concerning the “Conceptual Design of a Solar Powered Motor-glider", whereas her bachelor thesis addressed the study of “Deorbiting Strategies for Miniature Satellites”.     Greta Ongaro is currently taking part to a research project focused on the detection of damages in aeronautics and aerospace structures. In particular, she is studying and implementing coupled numerical methods for the analysis of static and dynamic crack propagation and developing multiscale numerical approaches for the mechanical characterization of nanocomposite materials, under the supervision of Prof. Ugo Galvanetto and Prof. Mirco Zaccariotto.  

Research project
The main aims of the research project are the following:  
I.  Study of Finite Element Method (FEM)-Peridynamic (PD) coupling strategies for static and dynamic crack propagation analyses;
II.  Improvement of the in-house FEM-PD coupling software: study of tools for FEM analysis and writing of subroutines to insert PD codes into commercial software, providing them with the capability to simulate damage initiation and crack propagation phenomena;
III.  Development of reliable simulations of wave propagation in the presence of cracks;
IV. Development of a full PD multiscale framework for the prediction and characterization of the mechanical properties of nanocomposite structures;
V.  Validation of numerical simulations through experimental activities.
