Ultrasound propagation in porous rocks: Theory identifies three distinct wave modes

Researchers developed a unified theoretical framework for ultrasound wave propagation and energy dissipation in porous rock formations. The study identifies three distinct longitudinal-wave types with different physical origins, providing a basis for understanding and predicting ultrasonic wave behavior in multiphase porous media.

Past the breaking point

Researchers from the University of Tokyo simulated fracture in amorphous solids to better understand material fatigue. They found that the critical strain for irreversible deformation is the same for both fatigue and monotonic fractures.
