Learning objectives
Students acquire the ability to use spatial elements for structural modeling. Starting from the approach to linear calculations, students learn the application of stability analysis using FEM. In doing so, the students learn the importance of the approach when considering geometric and physical nonlinearities. Furthermore, the students learn to interpret the calculation results and iteration progressions. At the end of the course, what has been learned is extended to the dynamic analysis of systems. The goal is to automate FE calculations using the Python programming language in the form of scripts on the Abaqus platform.
