A Critical Analysis on the Friction Modeling in Orthogonal Cutting of Steel
2007
Numerical simulation of cutting process is today moving towards two different directions. The former concerns the development of high performance codes able to approach the 3D phenomena, the latter is already focused on the study of some fundamental aspects whose full understanding may be strategic for the knowledge enhancing in this very complex field. In the paper this second way was pursued and a wide analysis on the numerical robustness of the 2D orthogonal cutting process is presented. In particular, the role played by the friction modeling is discussed taking into account a wide integrated numerical and experimental campaign.
Dark Spots in Trade Theory: Early Testing Attempts
2020
The beginnings of the economic theory correspond to philosophers’ attempts to explain why and how do countries trade with each other. Yet even more puzzling was the question how should countries trade? It is no surprise that despite the formidable developments of the theory in the last 200 years plus, there still are dark spots in the economics of trade. Globalization has rendered the issue even murkier. Beside the fact that international trade cannot be insulated from other economic domains, which makes it inadequate for experiments, but even testing itself is cumbersome. Only, evidence on such a complex field as international trade is by no means easy to come by.
