Comparative analysis reveals differences between static and dynamic Young's modulus in rock specimens, highlighting distinct mechanical responses under varying loading conditions.

Key Points

Compare statically and dynamically determined measurements of Young's modulus across rock specimens to assess variations in elastic mechanical properties.
Evaluated elastic deformation behavior of rock materials under direct static mechanical loading.
Determined dynamic elastic properties through acoustic wave propagation and vibrational testing methods.
Identified systematic discrepancies between statically and dynamically derived Young's modulus values across rock samples.
Demonstrated that dynamic elastic measurements consistently exceed static values due to differences in strain rate and microcrack closure.
