资源简介:

The experimental data are obtained using nonlinear resonant ultrasound spectroscopy on a sandstone sample. The experimental setup and signal processing are described in "The role of fast and slow dynamics in nonlinear resonant ultrasound spectroscopy of consolidated granular materials" by Kober et al. (2025).
