• A newly developed fracture model is employed to simulate three-diamensional fragmentation of tempered glass. • The model captures key fracture features, including branching and merging cracks, crack arrest, and secondary delayed crack formation. • Glass specimens with varying diamensions, pre-stress levels (including relatively high stresses) and diffrent fracture initiation conditions are considered. • Numerical results for fragment number and mean perimeter are compared with experiments on specimens of varying thicknesses and pre-stress levels. • The present fracture model captures the main physics of tempered glass fragmentation.
