The elastoplastic analysis of a tunnel using the EFG method: A comparison of the EFGM with FEM and FDM

作者：

Highlights：

• We present the new application of the EFGM in the elastoplastic analysis of tunnels.

• The results of the EFGM are compared with the results of the FEM and FDM.

• An increase in the number of nodes leads to a decrease in the interpolation spectrum.

• The results of the EFGM are in accordance with the results of the FEM and FDM.

• EFGM is capable of analyzing problems associated with elastoplastic behavior.
