Synopsis

EAS443 Finite Element Analysis of Aerospace Structures introduces fundamental concepts and procedures of the Finite Element Method (FEM) for calculations of stress, strain, and deformation in structures and materials. Some necessary background in solid mechanics is briefed as to the foundation of FEM theory. Various finite element formulations and applications to one-, two- and three-dimensional problems in solid mechanics are central to the course. This course also describes the role of a commercial finite element package in aerospace structural analysis and design. The engineering practice of finite element analysis such as geometric modelling, mesh design, material constitutive behaviour, Verification and Validation (V&V) is introduced. Students are expected to carry out one or more projects with the software package independently by developing life-long learning skills. The course is for students with an interest in developing a career path in aerospace research & design.
