Abstract: The spatial component of subsurface engineering data has historically been ignored because of the lack of appropriate analysis tools and techniques to account for this information. The development of powerful computed-based ...

Abstract: The effects of the confining membrane in laboratory tests on soil specimens have been the subject of numerous experimental, analytical, and numerical studies over the past half-century. This technical note expands the ...

Abstract: Improved design methods that allow for more accurate prediction of interface performance are needed as the number and types of interface strength dependent geotechnical systems being used in practice continues to increase. ...

Abstract: An investigation of shear mechanisms at interfaces between particles and relatively smooth materials using contact mechanics and basic friction theory reveals that a combination of sliding and plowing governs dense Ottawa ...

Abstract: Quantitative measurements of the local void ratio distribution are used to demonstrate how the microstructure throughout dilatant triaxial specimens of uniform fine quartz sand evolves during drained axial compression ...

Abstract: Nonuniformity within specimens of granular materials is considered to be one of the major reasons for the dependence of the observed static/dynamic response during laboratory testing on the method of preparation. In this ...

Abstract: As the use of the cone penetration test (CPT) has increased for geotechnical site characterization, significant research has been performed to identify and control the factors that affect the tip (
