Softening Amelioration of Duncan-Chang E-B Model Based on FLAC3D

CICTP 2012, 2012
It was discovered that the tri-axial experimental data of soil and rocks can be simulated using the Duncan-Chang E-B model in FLAC3D, and the model data are coincident with early stage loading experimental results. However, with increasing loads, once the simulation curves pass through a certain point, the axial strains show nonlinear growth with an ...
