The project aims to develop a complete multiscale framework for characterising and predicting energy dissipation and dynamic failure evolution in brittle materials under high strain rates.
Keywords:
Dynamic brittle fracture, energy dissipation, multiscale modelling.
Energy dissipation in dynamic fracture of brittle materials is pivotal in mining, civil engineering and defence. During dynamic brittle fracture, there are several main energy dissipation mechanisms, including new surface creation via fracture, fragment kinetic energy, acoustic emission, heat and friction. while the existence of these energy dissipation mechanisms is accepted, their actual contribution to the phenomenon remains unknown, largely limited by previous experiments. The project aims to develop a novel experimentally-validated multiscale theory, with associated models, for characterising and predicting the complete dynamic fracture process of brittle materials. This theory is expected to generate close-to-reality simulations critical for understanding fundamental aspects of energy dissipation in dynamic fracture. The outcomes will enable an optimised control of the fragment size in block cave mining and mineral processing, forecast and prevent fatal rock bursts in underground mines, and minimise catastrophic failures in critical infrastructures challenged by extreme loading, e.g. explosions.
