| Abstract: | Abstract: A new endochronic plasticity model that has the capability to describe both densification and dilatancy is described and applied to laboratory data from reconstructed ISST soils generated by the US Army Engineer Waterways Experiment Station. An efficient, explicit numerical scheme is developed for integrating the system of equations which govern the new model, and a corresponding computer program for, the numerical scheme is given. In numerical studies conducted with the computer program, it was found that situations arise where the calculated intrinsic time increment takes on inadmissable values; this difficulty does not appear to be of numerical origin but instead due to the particular mathematical representations adopted in the model for some of the material functions. Further study is recommended to explore this problem. |
