| Abstract: | Based on DAWNING 4000A supercomputer and LS-DYNA 970 MPP software, a large-scale three-dimensional dynamic simulation of cutting by the cutterhead in shield machine is performed with the use of arbitrary Lagrangian-Eulerian formula, MAT 147 material model and recursive coordinate bisection algorithm. According to the computing results, in-depth researches are also carried out with respect to soil big deformation, stress in the cutterhead and parallel computing effect. |
| Keywords: | arbitrary Lagrangian-Eulerian soil cutting parallel computing |
