heal.abstract	The current work addresses an impact - contact problem which simulates the impact of two bodies of different Young modulus. In particular, the case applied in this thesis refers to a body coming into contact with an approximately 1000 times less stiff body. Modelling, discretization and the solution are implemented in C# programming and, consequently, results are validated through the “Abaqus” software. More specifically, a circular ring and a rectangular body are being discretized by four-noded quadrilateral elements, whilst contact is enforced by the ring’s initial velocity. “Node to Segment” contact elements will be employed as the “bridge elements” among locally separated but, potentially interacting, surfaces. In addition, the well-known “penalty method” will be applied to the aforementioned contact problem. In order to reinforce our understanding of the present analysis approach, we briefly introduce the theoretical (i.e., physical and mathematical) framework of impact-contact mechanics that will be later applied to our application problem.	en
