Abstract
The great challenge to study the application involving large deformations is a choice of suitable constitutive law to simulate the soil response during installation of displacement piles. Considering, the nonlinear response, stress history, stress pass and the hardening/softening behavior for constitutive law assess to achieve the realistic behavior of piles during installation. In this study, the large deformations response associated with pile jacking are considered using a novel numerical approach which it calls coupled Eulerian-Lagrangian method (CEL). The used constitutive laws in study herein are partly based on elastoplastic theory while the other based on hypoplastic theory. Mohr-Coulomb and Cap plasticity constitutive law based on elastoplastic theory are adopted, while the Hypoplastic constitutive law formulated by Von Wolffersdorff was implemented using a material subroutine (VUMAT). The used constitutive laws are firstly calibrated with database of Hostun sand to simulate the jacking pile and investigate the response of pile using the corresponding constitutive law. Secondly, using the results of laboratory-scale at purdue university for jacking of pile into silica sand of #2Q-ROK are compared with numerical results to investigate the more realistic constitutive law with geotechnical applications involving large deformations such as jacking pile into sandy soil.
