Description This module introduces more advanced finite element analysis concept to engineering students who are already familiar with the application of the finite element method. The focus of this module is on advanced concepts such as non-linear materials and dynamic analyses. A theoretical understanding of 2D and 3D elements is covered and students are required to demonstrate that they can confidently formulate problems using these elements. Practical case studies are used to illustrate advanced analyses involving non-linear materials, contact, dynamic loads etc. Students are required to carry out a project which involves using advanced modeling methods in order to arrive at a solution. A choice of either a bio-engineering or a metal forming project is available. | |||||||||||||||||||||||||||||||||||||||||
Learning Outcomes 1. Apply the theoretical foundation of the finite element method to the solution of more advanced engineering stress problems. 2. Be able to formulate and solve a finite element analysis for simple 2D and 3D stress analysis problems. 3. Use commercially available FE software to solve advanced non-linear stress analysis problems. 4. Critically assess the results and accuracy from a FE analysis. 5. Be able to appropriately apply advanced concepts such as sub-modelling, sub-structuring, contact algorithms, multipoint constraints etc in a FE analysis. | |||||||||||||||||||||||||||||||||||||||||
