Título: Painéis curvos para aplicação estrutural
Área Científica: Construção metálica e mista
Síntese do Projeto: The objective of this research project is the development of advanced knowledge about the behaviour of curved panels that results in practical application rules and in a standardised FEM procedure for analysing curved panels. In fact, curved panels, either for aesthetic or structural reasons, are often used in bridge structures, ship structures, aircraft and submarines. However, curved panels are elements that have important stability issues, such as unstable post-critical paths (Martins et al, 2014). Additionally, existing design rules are insufficient. For example:
- European standards exclude this structural element: in EN1993-1-5 curvature is limited to b^2/(Rt)<1 (CEN, 2006)
- Other design rules are outdated: as recognized by the aerospace industry (Nemeth, 1998; Domb & Leigh, 2001) - And, finally, the rules proposed by the naval industry, DNV-RP-C202 (DNV, 2010), are based on ancient expressions that may be outdated).
Therefore, important advances in the understanding of the structural behaviour of curved panels are still needed.
Recently, this type of structural solution has been a central theme in several research projects: the POSICOSS and COCOMAT projects (both related to the aviation and aerospace industry and with focus on the analysis of composite panels excluding normalisation). This proposal differs from others by having a transversal approach to all areas of engineering that use curved panels as structural solution.
