文摘

Dynamic fragmentation of heterogeneous brittle materials is investigated. Fragment-size and fragment-mass results are obtained in glass, concrete and masonry. A new framework that incorporates heterogeneous strain rates has been proposed. This approach predicts the same fragment-size distribution as experiments.
