Learning objectives

KNOWLEDGE AND UNDERSTANDING
Students should demonstrate knowledge and understanding in order to develop new projects and implement original methods and techniques.
ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING
Critical evaluation of numerical results determined according to the assumptions on both modelling and intrinsic approximations of the finite element method. this assessment capacity appears to be essential in design and testing activities of engineers when commercial software packages are used.
ASSESSMENT AUTONOMY
Students should acquire the ability to integrate knowledge and to handle complex problems in the field of civil constructions by employing both new construction systems and advanced materials.
COMMUNICATION SKILLS
Students should be able to comunicate clearly and without ambiguity, to experts and non-experts, their results in the specific field of course topics, as well as the knowledges and where such knowledges aim.
LEARNING SKILLS
Students will develop the learning skills which will allow them to selfstudy.

Prerequisites

In order to be able to attend the course successfully, the student must have the knowledge of the basic finite element methods for the solution of engineering problems

Teaching methods

The course consists of theoretical lectures (20%) and practical exercises by using commercial software packages (80%).
Theoretical lectures are delivered by using slides available on the Elly website.

Assessment methods and criteria

The final exam consists of an oral test.
Such an oral test will be weighed as follows:
- 80% ability to solve numerically a structural problem by using finite element software packages (skills)
- 10% ability to answer theoretical questions (knowledge)
- 10% technical language knowledge (communication skills)
