- With reference to Dublin Descriptor 1 - knowledge and under standing, learning outcomes, expected and verified in the examination, are relative to the knowledge of following topics: modeling of the behavior of materials in elasto-plastic range, yield criteria, limit analysis, modeling of plane problems,stability of the structures. The main skills acquired (applying knowledge and under standing - Dublin Descriptor 2) are realtive the estimation of critical load and the collapse mechanism of structures,assessment of the strains/stresses in plane problems, estimation of instability load. As regards the calendar of the exams: http://www.ing1.unipg.it/didattica/studiare/34-calendario-appelli-esam
- Prerequisites
- Knowledge of structural mechanics and strength of materials: mechanics of solids materials, stress analysis, strain analysis, linear elasticity, mechanics of beam
- Teaching methods
- Theoretical lessons and practical training

- Learning verification modality
- The exam consists of an oral test. This is an interview aiming to ascertain the knowledge (Dublin Descriptor N. 1 - knowledge and understanding) level and the understanding capability (Dublin Descriptor N. 2 - applying knowledge and understanding) acquired by the student on theoretical and methodological contents as indicated on the program : Structural Non-linear Mechanics and Structural Dynamics. These topics have a very important significance in the professional role of civil engineer in the context of design and built of structures and infra-structures. The making judgements (Dublin Descriptor N. 3) and communication skills (Dublin Descriptor N. 4) are verified during the test.
