Numerical modeling of rock blasting: Validation tests for Blo-Up 2.5
Abstract: As part of the Hybrid Stress Blast Model (HSBM) project, Itasca has developed software to model the rock blasting process. The code, called Blo-Up 2.5, uses a unique combination of three-dimensional continuous and discontinuous numerical methods to represent the key processes occurring in non-ideal detonation, rock fracturing and muck pile formation. Itasca’s continuum rock ...
