Аннотация
Interaction between an open-end pipe and a soil plug is studied using Coulomb’s law of friction. The scope of the study embraces different models of soil and pipe. The finite difference solutions obtained for all models and the analytical solutions derived for some models describe the elastic process of the pipe and soil interaction. Agreement of the numerical and analytical solutions is shown. Results of different model calculations are compared, and the validity limits are determined for the models. The influence of Coulomb friction on pipe and soil movement is investigated.
