101015900L  Method of Finite Elements II  3 credits  2G  E. Chatzi, K. Tatsis  
Abstract  The Method of Finite Elements II is a continuation of Method of Finite Elements I. Here, we explore the theoretical and numerical implementation concepts for the finite element analysis beyond the linear elastic behavior. This course aims to offer students with the skills to perform nonlinear FEM simulations using coding in Python. *This course offers no introduction to commercial software.  
Objective  This class overviews advanced topics of the Method of Finite Elements, beyond linear elasticity. Such phenomena are particularly linked to excessive loading effects and energy dissipation mechanisms. Their understanding is necessary for reliably computing structural capacity. In this course, instead of blindly using generic structural analysis software, we offer an explicit understanding of what goes on behind the curtains, by explaining the algorithms that are used in such software. The course specifically covers the treatment of the following phenomena:  Material Nonlinearity (Plasticity)  Geometric Nonlinearity (Large Displacement Problems)  Nonlinear Dynamics  Fracture Mechanics The concepts are introduced via theory, numerical examples, demonstrators and computer labs in Python (starting Fall 2021). Upon completion of the course, the participants will be able to:  Recognize when linear elastic analysis is insufficient  Solve nonlinear dynamics problems, which form the core for limit state calculations (e.g. ultimate capacity, failure) of structures  Numerically simulate fracture; a dominant failure phenomenon for structural systems.
