Fracture is one of the most commonly encountered failure modes of engineering materials and structures. Computational modelling of fracture is very challenging due to complex evolution of the sharp crack-front. Nonetheless, the phase-field methods (PFMs) are very promising, where the sharp crack is approximated as a thin band of damage with a bandwidth proportional to the considered length scale. The thesis presents a PFM for fracture of brittle and quasi-brittle solids subjected to static, dynamic, thermal, and chemical loading. The proposed model is more accurate, efficient, and robust than existing models; hence it is suitable for predictive modelling of fracture.
