Standard penetration testing in a virtual calibration chamber [PDF]
Computers and Geotechnics, 2019 The virtual calibration chamber technique, based on the discrete element method, is here applied to study the standard penetration test (SPT). A macro-element approach is used to represent a rod driven with an impact like those applied to perform SPT. The rod is driven into a chamber filled with a scaled discrete analogue of a quartz sand.

Estimation of deformation modulus of gravelly soils using dynamic cone penetration tests
Ain Shams Engineering Journal, 2013 Estimating the deformation modulus of gravelly soils is a challenging task. The estimate of deformation modulus of cohessionless soils in general relies on availability of correlation between in situ test parameters and deformation modulus back ...
