4) Research activity
4.1) Geometrically nonlinear analysis of elastic structures.
Analysis of slender elastic structures through the asymptotic Koiter approach or by means of path-following methods in a finite elements numerical context. The computer codes developed concern trusses, framed structures in 2D and 3D, thin walled structured modeled as both a 1D or a 2D continuum. The research was initially funded by Alenia S.p.A. and by the European project Brite- EURAM " APRICOS ,"
Aspects investigated are:
− Analysis of the numerical and theoretical accuracy of the FE implementation of the Koiter asymptotic analysis and comparison of the results with those of path-following analyses.
− Asymptotic formulations in presence of coincident or almost coincident buckling modes.
− Sensitivity analysis and determination of the most dangerous directions of the imperfection in case of coincident buckling modes
− Mixed formulations in stresses and displacement to sanitize nonlinear locking problems due to the FEM model (locking due to interpolation) and the representation of the nonlinear
equilibrium path (extrapolation locking)
− Development of corotational formulations for asymptotic analysis.
− Parameterization of 3D rotations and use in the asymptotic context of analysis
− Determining of the order of infinitesimal mechanism of kinematically indeterminate systems a mechanisms.
4.2) Structural models for the analysis of nonlinear structures
Determination of structural models for beams, plates and shells suitable for the FEM analysis of geometrically nonlinear structures. The implicit corotational formulation proposed allows to obtain accurate nonlinear models of beam and plate from a parent linear solution, as for example that of De Saint Venant. This leads to rich structural models, obtained in a coherent and simple fashion, while frame invariance with respect to rigid rotations is automatically ensured.
4.3) Shakedown analysis
Extension of the classical strain - driven formulations used to assess the equilibrium path of elastoplastic structures to shakedown analysis. The algorithm is based on the proximal point method and a dual decomposition strategy. It presents the same characteristics of robustness, efficiency and convergence of the classical strain driven formulations. The comparison with interior point methods emphasizes the similarities between the two ways to proceed.
