Propagation behavior of two collinear mode Ⅰ cracks driven by explosive gas
In smooth pre-splitting blasting, two collinear cracks extending opposite to each other between adjacent holes will first avoid each other and then attract each other, resulting in crack propagation path that often presents hooked or butterfly-shaped loops.Based on the maximum tensile-stress criteri...
