A large strain theory and its application in the analysis of the cone penetration mechanism

摘要: the authors note, this is a very difficult problem to solve, even numerically, since it involves large deformations, moving boundaries and non-linear material behav- iour. The have used an axi-symmetric finite element analysis presented numerical results for displacement, stress pore water press- ure fields around cone tip at failure penetra- tion under undrained conditions. Failure defined as condition where penetration proceeds in- definitely constant pressure. Results are also given relationships between resistance depth. In reported in paper was assumed that initial effective state soil hydrostatic with magnitude of
