| 英文摘要 | This paper introduces the Goodman contact element based on the virtual element method framework. Since the virtual element method can calculate polygonal elements with any number of nodes, the limitation of mesh matching of the contact part required by the Goodman contact element is overcome by adding nodes to the contact element. Combine the virtual element method with the Goodman contact element to enable the Goodman contact element to solve practical problems in geotechnical engineering. In this paper, first, we derive the elastoplastic virtual element equations, and then, the Goodman contact stiffness matrix based on the virtual element method is calculated. Finally, several numerical examples are shown. In numerical models, the sensitivity of the virtual element method to mesh distortion is studied. We also investigate the shape sensitivity of the algorithm and the convergence of the Voronoi element through several frictionless contact examples. And then, the contact examples under friction state and elastic-plastic constitutive law are carried out. Finally, the contact force between soil and wall under the non-matching mesh in the gravity retaining wall commonly used in geotechnical engineering is presented. |
