Abstract EN
The study of rock blasting failure pattern is of engineering importance.
In order to investigate rock blasting failure pattern with one free boundary, high-speed photography technology is introduced into the two-dimensional granite model.
Through high-speed camera images, a crack that originated from spalling is observed and then propagates inward.
By using the high-speed digital image correlation method, the full-strain fields on the surface of the specimens are calculated.
The preliminary results show that von Mises strain localization appears on the specimen surface near the free boundary.
The axial strains near that crack present three kinds of characteristics.
There are the joint action areas of the strain localization by analyzing strains in different directions, and the strain localizations are related to the crack propagation.
Ultimately, after analysis of the experimental results, the preliminary diagrammatic drawing of rock blasting failure pattern under stress wave action with one free boundary is drawn.
