A profound study of the final causes of the appearance of defects within materials, and the need to establish a connection between the macroscopic behaviour of the mechanical components and the microstructure of the materials, calls for a change in scale with respect to that of classical methods and a step forwards towards a study on the level of inter-atomic distances.
This area is centred on deepening the knowledge of the mechanisms that control the mechanical behaviour of materials with crystalline structure on a nanometric scale by atomistic models of discrete networks, starting from the discrete dislocation theory developed by the members of the research group.
Experimental analysis of defects
The experimental analysis of defects in materials can be carried out by techniques which allow certain important properties for analysing their performance under fracture to be obtained. An important example of this is the determination of the resistance to fracture of materials or the stress intensity. The study of the dynamic spreading of cracks can be carried out using specific research techniques, such as fatigue testing.
Experimental analysis of cracks in concrete
Crack spreading is a common phenomenon in concrete. Experimental determination of certain parameters such as fracture energy or stress resistance is fundamental for using to analyse the performance under fracture of concrete. Numeric models often require prior experimental determination of these parameters.
