摘要

This work is the final report of the activity developed in the frame of the european project EUREKA-FASP (EU353) concerning the numerical simulation of the processes of the hot shaping or bending of large sheets, of interest of the ship-buildings, by the use of ABAQUS code in its implicit version (ABAQUS/S). The work has been subdivided in 6 parts according to different considered aspects and made choices. Substantially, two different types of sheet heating processes have been considered, that is 'Line Heating' and 'Area Heating' processes, while two aims have been pursued: (1) to single out the best strategies in order to simulate the shaping of large sheets in a suitable way, corresponding to the experience, adopting thermo-structural computation codes, as ABAQUS; (2) to verify and suggest, in some cases, orientations and indications for the design of an automate machine managed by an expert system (one of the aims of FASP project) for the heating of large sheets, able to provide the required shaping or bending of these sheets.
