报告题目：Classical and Advanced Computational Beam/Plate/Shell Models for Laminated Structures subjected to Multifield Loadings
This talk will shortly present activities at MUL2 group of Politecnico di Torino in terms of project description and ongoing research. The seminar is devoted to discussing classical and advanced methods to analyze structures loaded by thermal and electrical field loadings . Beam, Plate, and Shell Formulation will be first overviewed. Interlinear continuity, zig-zag theories, equivalent single layer, layer-wise, displacement, and mixed formulation will be part of this talk. The need of refined models will be outlined in case of constant or variable thought-the-thickness (or over the section in case of beams) fields loadings. The Carrera Unified Formulation, CUF, will be used to shows the various modeling and to obtain Finite Element solutions. The component-wise approach will be therefore introduced along with Variable Kinematic approaches and Node Dependent Kinematic schemes. Finally, some guidelines on the choice of the best-generalized variables for high-fidelity, and low cost with a particular focus on multifield and perspectives on machine learning assisted structural analyses.
Erasmo Carrera is Professor of Aerospace Structures and Aeroelasticity at Politecnico di Torino, Italy, where he graduated in Aeronautics, 1986, and Space Engineering, 1988. He earned a Ph.D. in Aerospace Engineering in 1991. Carrera has introduced the Reissner Mixed Variational Theorem, RMVT, as a natural extension of the Principle of Virtual Displacement (PVD) for layered structure analysis. He introduced the Unified Formulation, or CUF (Carrera Unified Formulation), as a new framework to develop linear and nonlinear theories of beams, plates, and shells for metallic and composite multilayered structures under mechanical, thermal electrical and magnetic loadings. Carrera is author and coauthor of about 800 papers and a few recent books. He is founder and leader of the MUL2 group at Politecnico di Torino. The MUL2 group has six staff members and some 15 grad students or Post-Docs with a project portfolio of some ten active projects funded by the European Commission, the Italian government, Politecnico di Torino and industrial partners such as Embraer.
