Paper presented at the ISRM International Symposium – EUROCK 2021, September 21–24, 2021
Paper Number: ISRM-EUROCK-2021-113
... Abstract Rockfall fragmentation is a very complex phenomenon that is still poorly understood and modelled. Being able to adequately model fragmentation of impacting blocks, including change of shape, size, and energy after breakage, is essential to be able to predict realistic trajectories...

...) and igneous rocks (granitoids and dolerite). A back propagation artificial neural network was developed and trained in order to predict UCS. The input parameters were unit weight γ, (Is ( 50 )), (σ t ), and lithology. The lithology was introduced in the neural network as a qualitative input parameter...
