Dr. Erasmo Carrera is the President of A.I.D.A.A. Associazione Italiana di Aeronautica ed Astronautica. He is the Local Chairman of IAC 2024 Milano and ICAS 2024 Florence. He is Professor of Aeronautics and Astronautics at Politecnico di Torino, Italy. He graduated in Aeronautics in 1986 and Space Engineering in 1988 at the Politecnico di Torino. He obtained a Ph.D. in Aerospace Engineering in 1991. He introduced the Unified Formulation, or CUF (Carrera Unified Formulation), as a tool to establish a new framework in which to develop linear and nonlinear theories of beams, plates and shells for metallic and composite multilayered structures loaded by mechanical, thermal electrical and magnetic loadings. Carrera has been author and coauthor of about 800 papers on the above topics, most of which have been published in first rate international journals, including a few recent books. Professor Carrera is founder and leader of the MUL2 group at the Politecnico di Torino.The MUL2 group has acquired a significant international reputation in the field of multilayered structures subjected to multi field loadings, see also www.mul2.com. Professor Carrera has been recognized as Highly Cited Researchers (Top 100 Scientist) by Thompson Reuters in the two Sections: Engineering and Materials (2013) and Engineering (2015). He currently acts as President of AIDAA (Associazione Italiana di Aeronautica ed Astronautica). He has been a recipient of JN Reddy Medal. Editor in-chief of Mechanics of Advanced Materials and Structures by Taylor & Francis, funding Editor of Advanced in Aircraft and Spacecraft Sciences by Techno-Press. Due to his scientific out coming professor Carrera has been recently awarded by the President of Italian Republic, as ‘Honoray Commendator’. It consist of one of the highest award in Italy and it has been given to only 90 Italian Scientists from 2003.
Nonlinear phenomena dominate many engineering problems in various fields. At least one of the three main nonlinearities is often involved: geometrical (stability), physical (material nonlinearities) and unknown boundary condition (contact, impact). Finite Element Methods is by decades the most suitable computational method for both linear and nonlinear problems. Linear problems consist of one-shot analysis, nonlinear ones require multi-shot analysis. This simple fact is the most significant distinction between linear and nonlinear analysis; that is the approximation, e.g. errors in linear analysis, could propagate in a multi-shot case. Therefore, in order to solve in a suitable manner nonlinear problems very efficient ‘ as a whole’ numerical models are required. It is a well-known fact that assumption of classical beam, plate and shell theories often lead to solutions that could deviate significantly from the exact ones. On the other hand, the use of simplified nonlinear relations (such as von Ka’rma’n approximations) could lead to large errors to detect the correct solutions when the equilibrium path is far from the unreformed configurations. In recent years, the author and co-workers have successfully introduced and extended the Carrera Unified Formulation, CUF, which is a hierarchical framework to develop any theory of structures for beams, plates and shells including laminated structures and multifield loadings. These have been extended and applied to various nonlinear problems with excellent and unique accuracy. FEs applications have been developed extensively. It has been shown that such accuracy could be only achieved by the use of solid-3D Finite Elements if commercial software is referred to, nevertheless, the computation costs of 3D analysis could become prohibitive. This talk will first overview some of the most interesting problems solved by CUF: buckling and post-buckling of thin-walled structures, plasticity, progressive failure in laminates, low-velocity impact. The extraordinary advantages of CUF usage with respect to other models will be made clearly evident. Particular attention will be given to the application to stability analysis in both linearized and nonlinear cases, via the so-called vibrationcorrelation technique (VCT).
