Advanced Finite Element Simulations Using Abaqus
Technical University of Denmark
General course objectives:
The course will introduce the use of the commercial finite element code Abaqus in a research-oriented way where a number of nonlinear problems will be addressed. The focus will be on creating, analyzing and evaluating nonlinear material simulations, simulations of fibre reinforced composites and crack growth predictions.
Learning objectives:
A student who has met the objectives of the course will be able to:- Create advanced finite element models in Abaqus
- Apply theoretical concepts to analyze finite element simulations
- Apply the effects of nonlinear material models and evaluate the results
- Create models consisting of orthotropic materials and analyse its influence
- Create models discretizing fiber composite structures and analyse the layups and critical ply stresses and strains based on first and last ply failure criteria
- Create and evaluate crack tips models and analyse their prediction accuracy.
- Create crack growth using models cohesive material laws in a finite element model and evaluate the impact of different modelling parameters
- Create Python scripts and apply these for pre- and post-processing steps
- Apply Large-Language Models like ChatGPT/CoPilot to generate scripts and input files in order to interact with Abaqus and to evaluate/post-process results.
- Create simple user-defined subroutines in Abaqus
- Understand the navigation in Abaqus’ User Manual and apply your knowledge to find relevant information.
- Analyse and evaluate critically finite elements simulations (plausible check, physical meaningful, mesh convergence study, comparison with tests/analytical results).
Contents:
The workload in the course will focus on the study of a number of nonlinear problems, which include building up, solving and evaluating the solutions from realistic finite element problems. Throughout the work with the finite element exercises, important points using a commercial finite element code will be addressed. Cases involving isotropic elastic, anisotropic elastic and elastic-plastic material laws will be studied. In addition, user-defined subroutines and Python scripting be will used.
