Project

Solid body fracturing mode by shear-tensile source model acoustic emission laboratory study (GA16-03950S)

. We will detect and classify the shear and tensile modes of rock fracturing as the impact of microcrack concentration and orientation on the fracture mode changes. A novel source model consisting straight from the...
