The fracture behaviors of rocks under dynamic loading are significantly affected by flaws. Understanding regarding this fundamental mechanism flaw-induced fracturing could aid in reducing geohazards deep rock engineering. In study, a series experiments conducted on conjugate flawed white sandstone specimens to study the effect geometric configuration flaws fracturing. results show that geometry...

Fundamental to the ability to monitor a Comprehensive Nuclear-Test-Ban Treaty is a good understanding of the nuclear explosion source. Considerable research has been done on the nuclear explosion source over the past 30 years, with mixed success. Although empirical and numerical models of explosion sources do a fairly good job of matching observed seismic signals, a good explanation of the phys...
