Thermomechanical analysis of the tensile test: simulation and experimental validation
Celentano, Diego J. Techno-Press 2002 Structural Engineering and Mechanics, An Int'l Jou Vol.13 No.6
This paper presents experimental and numerical analyses of the thermomechanical behaviour that takes place in SAE1020 mild steel cylindrical specimens during the conventional tensile test. A set of experiments has been carried out in order to obtain the stress-strain curve and the diameter evolution at the neck which allow, in turn, to derive the elastic and hardening parameters characterizing the material response. Temperature evolutions have also been measured for a high strain rate situation. Moreover, a finite element large strain thermoelastoplasticity-based formulation is proposed and used to simulate the deformation process during the whole test. Some important aspects of this formulation are discussed. Finally, the results provided by the simulation are experimentally validated.
The Situation Lens: A Metaphor for Personal Task Management on Mobile Devices
Celentano, Augusto,Faralli, Stefano,Pittarello, Fabio Korean Institute of Information Scientists and Eng 2009 Journal of Computing Science and Engineering Vol.3 No.4
In this paper we discuss personal data management with mobile devices, an activity requiring the composition of services offered by standard suites of applications. We propose a data model and an interface model that allows users to define activities, tasks and services, to navigate among them according to the evolution of the personal situation as perceived and interpreted by the users themselves. The interface model acts as a lens exploring the situation, zooming into the details, covering different areas of the personal data, supporting the user in the role of a composer of personal services.
