Numerical Study on the Fracture Properties of Concrete Shield Tunnel Lining Segments
Figure 8
Meshes for the cracked tunnel lining segment: (a) the uncracked global structure is molded with finite elements (10-noded tetrahedron elements); (b) the initial crack surface is molded independently with boundary elements (8-noded quadrilateral elements).
