FELSSO: Finite Elements with Laser Scanning for mechanical analysis of Sculptural Objects

The FELSSO project has used commercially available advanced 3D laser scanning technology to capture detailed 3D surface geometry data of the sculptures with these data then being converted into computer models of the original object that are then subjected to finite element analysis (FEA). Originally, it was planned to use sculptures in the Tate collection as the basis for the study. However, the Henry Moore Foundation has given permission for Moore’s travertine stone Arch to be used as the principal subject for the FELSSO study. FEA is a mature technology that I widely used in engineering to calculate the strength of structures such as buildings and aircraft, but with FELSSO it will be applied to sculptural artefacts in order to accurately model the probable impact that different handling or display scenarios may have on the sculpture in question. By working with the Arch, the research project will deliver a detailed practical strategy, based on FEA, for the physical conservation and redisplay of stone sculpture. In addition, the 3D data captured from the sculpture will be available for use by the Foundation in a variety of ways, including the computer aided manufacture of a scaled facsimile for display and educational purposes, and 3D models for virtual display and web based access.
