- Description
- A robust numerical method is suggested for dealing with the complex and difficult problem of analysing dynamic soil penetration and compaction. The approach is based on the Arbitrary Lagrangian-Eulerian (ALE) method of analysis, whose main features and challenges are briefly described. The method is then employed to perform a parametric study of a variety of penetrometers free-falling into layers of inhomogeneous clay deforming under undrained conditions. The effect of the mechanical properties of the clay soil on the penetration characteristics is discussed and some of the predictions are compared with the results of laboratory experiments. How these results might be used in the interpretation of in situ penetration tests is then suggested. The numerical method is also adopted to examine the fundamental compaction behaviour of soils and the trends in predicted results are broadly compared with the results of physical experiments.
