The course aims to provide the fundamental tools necessary for the modelling of the failure behaviour (in both the static and fatigue regimes) of brittle or quasi-brittle materials and structures. The attention will be focused to structural elements containing defects (such as cracks, V-notches, circular holes), and subjected to different loading conditions. The crack onset or crack propagation load is achieved by means of the Finite Fracture Mechanics approach, based on the assumption of a crack advance which is discrete (and not infinitesimal, as in classical LEFM). Theoretical predictions will be compared with experimental data rising from different engineering fields.
Theory of Elasticity
The course will be organized as follows:
- Fundamentals of linear elastic fracture mechanics (1.5 hours)
- Finite Fracture Mechanics. Different theoretical models (3 hours)
- Effects of a circular hole, a sharp or blunt V-nocth, and T-stress on the failure load in brittle structural elements (concrete, polymers, metals, rocks) subjected to different loading conditions. Interfaces and debonding. Static and fatigue failures: applications in civil, mechanics and aerospace engineering (7.5 hours)
