The installation of screw piles can cause damage to the soil. which is a dynamic and large deformation problem. In this paper. a FEM-SPH numerical model for the analysis of this large deformation problem was developed in LS-DYNA to simulate the installation process of screw piles. https://clgrsuj3yfh3j.bloginwi.com/68599011/remote-calibration-technology-in-target-rcs-time-domain-outfield-measurement
