... on the shear strength properties is specifically discussed. A relationship between the angle of internal friction and moisture content for residual soil is also proposed. Test results are then used to calculate the non-linear (hyperbolic) model constants and analyse the stress-strain response of the compacted...

.... Laboratory test results reported by many investigators (Holtz and Gibbs 1956, Morris 1959, Vallerga et al 1957) indicated that the angle of internal friction increased with increasing angularity. On the other hand test by Marchi and coworkers (Marchi et al 1969) showed that at low confining pressure...
