EFFECT OF VARIABLE LINEAR ELASTIC PARAMETERS ON FINITE ELEMENT PREDICTION OF SOIL COMPACTION
ABSTRACT An axisymmetric linear elastic finite element program was developed to investigate the effect that the two linear elastic parameters, Poisson*s ratio and Young's modulus, had on soil compaction. This program was verified against Boussinesq's linear elastic theory. It was found that increased values of Young's modulus had no effect on the stress state in the soil mass but that strain levels were decreased. Increased values of Poisson's ratio increased the stress state and decreased the strain levels. The interaction of these two parameters point to the need to be able to vary both over the entire stress range.
