DYNAMIC RESPONSE OF MARBLE AND
SANDSTONE UNDER ROTATIONAL STRESS |
|
|
|
Abstract After the phase difference between st ress and st rain was obtained , it is observed that oil2saturated rock
has more attenuation than water2saturated one , while the attenuation of dry rock is very small. The dependence of
attenuation on f requency is very st rong , and sandstone is of obvious anisot ropy. The variation t rend of attenuation ,
modulus and Poisson ratio with increasing amplitude of sinusoidal st ress is also of obvious anisot ropy.
