Elastic contact to a coated half-space - Effective elastic modulus and real penetration [PDF]
, 2004 A new approach to the contact to coated elastic materials is presented. A relatively simple numerical algorithm based on an exact integral formulation of the elastic contact of an axisymmetric indenter to a coated substrate is detailed.

Analysis of wedge penetration in clay [PDF]
, 1976 A variety of devices designed to penetrate soil is used in soil engineering practice to measure soil properties or to emplace instrumentation, although the mechanics of the steady state penetration process is not well understood.

The cone penetration test in unsaturated silty sands
E3S Web of Conferences, 2016 Very little is known about how to interpret the cone penetration test (CPT) when performed in unsaturated soils. The few published studies on the CPT in unsaturated soils have focused on either clean sands or a silt.

Investigation into the effect of uncertainty of CPT-based soil type estimation on the accuracy of CPT-based pile bearing capacity analysis [PDF]
, 2016 Cone Penetration Test (CPT or CPTu) is commonly used for estimating soil types and also for the geotechnical design of pile foundation. However, the level of agreement between the CPT-based soil types and the traditional identification of soil types ...
