Objectives
To provide students with advanced knowledge on nonlinear solid behavior and nonlinear analysis of structures.
Subject matter
- Causes of non linearity. Nonlinear elasticity. Plasticity, accumulated damage and fracture.
- Theory, modeling and calculation of structures with material or geometric non linearity. Strategies for resolution of nonlinear equations of equilibrium. Introduction to the nonlinear dynamic analysis of structures.
- Applications to concrete structures, with or without external reinforcement through plated polymers. Material behavior under monotonic, cyclical and dynamic loads. Effect of external confinement in elements subjected to compression. Steel-concrete adhesion and modeling of bond-slip between steel and concrete and between FRP reinforcement and concrete. Crack modeling. Representation of material aging in the behavior of reinforced concrete elements.

Teaching method
- Weekly meetings between lecturer and students, for introduction and development of concepts, assessment of the progress made and presentation and analysis of proposed exercises.
Evaluation method
- Evaluation based on individual activity report, focusing on the presentation of results to the problems suggested.
