... thermodynamic theory and finite difference method, the numerical simulation method and inversion method were proposed to simulate and explain the testing results. The results indicated that the simulated results are overall consistent with the test results, and the maximum relative error is about 28...

... on the multistage triaxial testing results. Two different stress paths were proposed in transition period from on going stage to the next stage. The first scenario was both axial load and confining pressure simultaneously increased. The second scenario was an axial load is kept constant while a confining pressure...
