A new theoretical paradigm to describe hysteresis,discrete memory and nonlinear elastic wave propagation in rock
new theoretical paradigm hysteresis discrete memory nonlinear elastic wave propagation
2009/11/16
The velocity of sound in rock is a strong function of pressure, indicating that wave propagation in rocks is very nonlinear. The quasistatic elastic properties of rocks axe hysteretic, possessing disc...
