Numerical Simulation on Damage and Failure Mechanism of Rock under Combined Multiple Strain Rates

<div>Model setup for SHPB test of rock under combined static and dynamic loading (unit: mm) [<a href="/journals/sv/2018/4534250/#B112">112</a>]: (a) model; (b) the waveform of dynamic stress <i>p</i><sub>d</sub>(<i>t</i>) with an amplitude of <i>p</i><sub>dm</sub> and duration of <i>t</i><sub>dm</sub>; (c) amplified rock specimen, in which 5 typical points where the stress or strain will be retrieved and averaged.</div>
