Intro to 2D and 3D Finite Element Analysis (FEA) with Ansys MechanicalTM Software
This lectures offers a thorough introduction to finite element analysis, covering both theoretical principles and practical applications. It explains the fundamental concepts of discretization and the transformation of physical problems into solvable systems of algebraic equations using the finite element method (FEM). The course covers the distinctions between linear and nonlinear FEM, as well as the critical role of meshing in ensuring convergence and maintaining element quality. It also explores various mesh methods and their implications for analysis accuracy. In addition, the differences between 2D simulations, specifically plane strain and plane stress cases, are discussed, as well as the significance of axial symmetry and the necessity for 3D elements. Five illustrative examples are provided to further clarify the practical applications of FEA. These examples utilize Ansys Mechanical™, a structural finite element analysis software, and Ansys Workbench™, a simulation integration platform.
