- Description
- Falling rocks commonly break up on impact, and the change in size, shape and energy of falling blocks can drastically change the outcome of rockfall risk assessments. However, fragmentation of falling blocks is poorly understood and often ignored. The current study presents the results of an experimental campaign aiming at investigating the influence of the impact angle on the fragmentation of homogenous prismatic blocks upon impact. More than 120 brittle masonry blocks were released from the same height to impact on a horizontal concrete slab with a wide variety of impacting angles. High-speed video recordings were used to determine the actual impact angle in each case. The results show that likelihood of fragmentation decreases when the impacts is directly on a face, and increases when the impact is on a corner or an edge.
