摘要: Abstract The design of Brazilian disc sample was used to investigate the tensile properties rock material in dynamic splitting tests. Two types samples were study accuracy unidirectional strain calculation method for discs, based on propagation stress waves at interface, and rationality results verified by experiments. stress-strain curves determined using loading data two samples, it found that inappropriate BD test under conditions. computational efficiency precision different methods determining Young's modulus-time evaluated. In addition, difference planar also determined. three stages modulus discs conditions are obtained, failure mechanism is analyzed during stages.
