Integrated course unit module: ADVANCED FINITE ELEMENT ANALYSIS

Learning objectives

• Learn the underlying basis for the deformation of beams and shells.
• Understand how the beam/shell structure and microstructure affects is overall mechanical response.
• Students will gain judgment skills for the design of beam, membranes and thin materials whose deformation is primarily governed by bending.

Course unit content

1. Concepts of differential geometry applied to curved structural elements.
2. Deformation measures on a curved beam/shell. Examples.
3. Stress and mechanical equilibrium.
4. Constitutive relation: from microstructure to macroscopic elastic behavior.
5. Numerical (iterative) solution for soft non-linear elastic beams and plane-strain shells.
6. Implementation using matlab.
7. Non-linear static analysis of the large deformation of beams and shells; examples and applications (in civil, mechanical engineering, material science and nature).

Teaching methods

The course is organized in theoretical and practical lessons (by making use slides or other kind of computer presentations); the exercises are either developed by the teacher and autonomously in class also by making use of the computer and at home by the students.

For every topic, the practical activities are properly scheduled in order to provide the students the ability to solve the proposed problems on the basis of the previously explained theoretical concepts.

Assessment methods and criteria

The final assessment consists in a single written test on all the topics covered by the course (with theoretical questions and simple numerical exercises). The students can also decide, on a voluntary basis, to improve the grading of their final exam by preparing a short report related to the analysis of a simple structure assigned by the teacher. This small project will contribute up to 30% of the final grading of the exam.
