Theoretical Analysis of Longitudinal Wave Attenuation in a Stressed Rock With Variable Cross-Section
Publikováno v:
Frontiers in Earth Science, Vol 7 (2019)
In this work, the longitudinal wave propagation in stressed rock with variable cross-section is investigated analytically. Considered the stress-sensibility of dynamic elastic modulus and the viscosity of rock, a modified viscoelastic stress-strain r
