Strain softening and instability of sand

The majority of experimental studies on strain
softening and instability behaviour of sand have been
carried out under axisymmetric conditions. However,
most geotechnical structures such as slopes,
embankments, and retaining walls, are not
axisymmetric problems and can only be simplified into
plane-strain conditions.
A comprehensive experimental study on the strain
softening and instability behaviour of a granular
soil under plane-strain conditions is presented in
this book. A new plane-strain apparatus was developed
and used. The main features of the new plane-strain
apparatus include appropriately enlarged and
lubricated rigid platens using the free-end technique
and four submersible load cells used for measurement
of the lateral stress.
In this study various specialised
plane-strain tests were carried out on very loose to
medium dense Changi sand retrieved from a reclamation
site in Singapore.
The experiments presented in this book should help
shed some light on strain softening and instability
phenomena of granular soils, and should be especially
useful to academics, researchers, and students, or
anyone else who may be interested in experimental
soil mechanics.

The majority of experimental studies on strain softening and instability behaviour of sand have been carried out under axisymmetric conditions. However, most geotechnical structures such as slopes, embankments, and retaining walls, are not axisymmetric problems and can only be simplified into plane-strain conditions. A comprehensive experimental study on the strain softening and instability behaviour of a granular soil under plane-strain conditions is presented in this book. A new plane-strain apparatus was developed and used. The main features of the new plane-strain apparatus include appropriately enlarged and lubricated rigid platens using the free-end technique and four submersible load cells used for measurement of the lateral stress. In this study various specialised plane-strain tests were carried out on very loose to medium dense Changi sand retrieved from a reclamation site in Singapore. The experiments presented in this book should help shed some light on strain softening and instability phenomena of granular soils, and should be especially useful to academics, researchers, and students, or anyone else who may be interested in experimental soil mechanics.
