Objectives
- From the mathematical point of view, knowledge of how to formulate a problem through the Finite Element Method, starting from the strong form of the differential equations, converting them to the weak form, and finally performing the spatial discretization of the problem, is expected.
- To develop different types of finite elements and assemble the matrices and vectors, which are relevant for the solution of problems in the Mechanics of Solids in terms of displacements. Programming the Finite Element Method for the calculation of solids and structures.
- Be able to use the Finite Element Method to solve practical problems in Mechanical Engineering through the use of numerical packages (e.g., ABAQUS).
Learning outcomes and competences
At the end of the course, the student must be able to formulate a problem using the Finite Element Method. He must also have the ability to develop an algorithm to simulate the mechanical behavior of solids and the capability to evaluate results for a wide range of problems.

Program
- Review of the application of energy methods in structural mechanics and the Finite Element Method: general presentation of energy methods with particular reference to theorems based on displacement formulations.
- Formulation of Finite Elements; General Method: definition, by stages, of the formulation of Finite Elements in terms of displacements.
- Dynamic Analysis by the Finite Element Method: Hamilton Variational Principle, consistently linearized mass matrix, numerical integration of the motion equation (Finite Difference Method and Newmark).
- Material non-linear problems, plasticity: physical motivation, mathematical model and computational aspects for one-dimensional problems. Interaction with the yield surface, Forward-Euler, and Backward-Euler algorithms, consistent tangent matrix.

Eligibility for exams
The final classification is the average of the classifications obtained in the component related to the assignments (25%) and the exam (75%). For each of the components, it is necessary to obtain a minimum grade of 7 (out of 20). Failure to obtain at least 7 (out of 20) in the assignment inhibits the possibility to do any of the subsequent examinations.
Calculation formula of final grade
Final Mark is based on the average grade of the assignment and exam. Minimum of 7 (out of 20) in each component of the evaluation.
Examinations or Special Assignments
An assignment on Finite Element analysis/programming.
Special assessment (TE, DA, ...)
A written exam. The computer assignment has to be done during the first semester.
Classification improvement
Students can improve their grade by attending resit exam.
