Abstract: This paper presents a theoretical study of Biot flow–induced damping in saturated soil during shear wave excitations. The solid skeleton is treated as equivalent linear. Biot flow–induced damping is evaluated for the cases ...

Abstract: Damping is an important dynamic soil property that has been well-studied on the continuum scale. However, particle-particle interactions that are responsible for damping in dry soil are relatively less studied due to the ...

Abstract: Application of the smoothed particle hydrodynamics (SPH) method to the simulation of granular materials under large deformation is presented. The Drucker–Prager constitutive model with nonassociated flow rule is implemented ...

Abstract: The stress-strain response of sand at high strain rate is an important topic. However, most of the numerical studies concentrated on sands at high water content and were not able to capture the softening and subsequent ...

Abstract: Split Hopkinson pressure bar (SHPB) tests have been used extensively to study the stress–strain behavior of sand under high strain-rate conditions. However, the low impedance of sand leads to specimens not attaining stress ...

Abstract: Slope stability prediction is an important task in geotechnical engineering which can be achieved through physics-based or data-driven approaches. Physics-based approaches rely on geotechnical knowledge from soil mechanics, ...

Abstract: Pile foundations are often subjected to lateral loadings. By adding steel plates (fins) to the side of the pile, steel fin pile foundations (SFPFs) can improve the lateral load capacity of piles. Existing numerical studies ...

Abstract: This technical note defines an “effective soil density” that controls the velocity of small strain shear waves in saturated soil. Biot theory indicates that the ratio of effective density to saturated density will generally ...

Abstract: A theoretical study of the steady-state response of a saturated poroelastic soil column during compressional and rotational harmonic vibrations is presented. Hydraulic damping due to Biot flow is evaluated for top-drained ...
