Abstract: An elastoplastic, finite-strain, coupled theory of mixtures in an updated Lagrangian reference frame is applied to the piezocone penetration test to estimate the hydraulic conductivity of the soil via analysis of the ...

Abstract: There are several approaches that can take into account the micromechanical and anisotropic behavior of soils. One is Dafalias's plastic spin approach. It is a convenient approach that utilizes an internal variable called ...

Abstract: Micromechanical and anisotropic behavior of soils is analyzed using the plastic spin and anisotropic modified Cam clay model (AMCCM) in an updated Lagrangian reference frame. The micromechanical behavior of soils is ...

Abstract: A new method of estimating the permeability of soils using an acoustic technique is proposed in this technical note. Biot’s coupled theory of mixtures from the mid-1950s, which addresses the relationship between the ...

Abstract: During Hurricane Katrina, overtopping water caused erosion and subsequent failure of several sections of I-type flood walls in New Orleans. Erosion stemmed from the kinetic energy of water falling from the top of the flood ...

Abstract: T-walls in New Orleans survived Hurricane Katrina whereas I-walls obviously failed in several sections. However, it is still unclear whether these T-walls truly survived the hurricane with a fair amount of safety margins ...

Abstract: Erosion was one of the major causes for the failure of New Orleans levee system during Hurricane Katrina. Protection of flood walls from erosion failure can be achieved in many different ways. This study consisted of ...

Abstract: There is a growing interest in relating nanostructures to the macro properties of engineering materials such as composites and cement materials. Better understanding of structure and elastic properties of nanoparticles in ...
