Abstract

This discussion starts with a general assessment of the capabilities of several types of laboratory shear devices and their corresponding suitability for use in specialized design practice and for basic research into the constitutive stress-strain-strength relationships of soils. It then focuses in greater depth on two specific topics: use of the Geonor Direct Simple Shear (DSS) device for design practice involving soft clays, and experimental requirements needed to reliably measure stress-strain-strength behavior in cross anisotropic soils.
