Abstract

This lecture is concerned to the developments of Unified Formulation (Carrera Unified Formulation, CUF) to solve some nonlinear problems. Enhanced 1D and 2D (beam/plate/shell) formulations are constructed by the condensed CUF notation. The capability of 1D-CUF models to develop component-wise CW approach for the analysis of metallic and composites aerospace wing, fuselage full-aircraft structures is addressed. CW is also applied for accurate evaluation of 3D stress fields in the lamina components (fiber and matrix) and to typical free edge problems and progressive failure analysis PFA of laminates are overviewed. Applications to Nonlinear problems (plasticity, large deflection and post buckling and contact) are overviewed. The use of Global-Local approaches is discussed.

Dr. Erasmo Carrera is the Professor of Aerospace Structures and Aeroleasticity at Politecnico di Torino, Italy, where he graduated in Aeronautics in 1986 and Space Engineering in 1988. He obtained 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 to layered structure analysis. He introduced CUF (Carrera Unified Formulation) as a tool to establish a new framework in order 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 co-author of about 800 papers on the above topics, including a few recent books. Professor Carrera is founder and leader of the MUL2 group at the Politecnico di Torino. 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 is Editor-in-Chief of Mechanics of Advanced Materials and Structures; founder and Editor-in-Chief of Advanced in Aircraft and Spacecraft Sciences; acts as President of A.I.D.A.A.
