Let (9) then (10) where ETI* is an effective modulus for transversely isotropic materials.
Obtain the degradation data (material properties) of the contact zone from the results of the progressive damage analysis. 2.
The following conclusions can be drawn from the present study: (1) The degradation data of the material properties could be obtained from the results of the progressive damage analysis by linking the non-liner analysis with user-defined material (UMAT)

After groundwater corrosion, tunnel lining material becomes loose, material strength decreased, causing landslides, falling rocks and other issues.
At the medium stage, Samples surface becomes rough dark in color, the area of ​​white marks expand, show ion reaction has occurred in cementations materials and aggregates up the phenomenon of sand slightly.
Indicate that solution and the material has been reflected adequately.
The interior material is smooth before corrosion.
