The behaviour of clay in simple shear and triaxial tests [PDF]
The main objective of this work is to study the applications of critical state soil mechanics to simple shear testing. The problems with the simple shear apparatus and the approach for interpreting simple shear test results are described. Laboratory tests were conducted using the NGI simple shear apparatus, standard shear box arid computer controlled ...
