SUMMARY, CONCLUSIONS AND RECOMMENDATION FOR FUTURE WORK
9.2 Recommendation for Future Work
(1) Simplify the fuzzy-set plasticity model and enhance the applicability of the model by reducing the number of the model parameters as much as possible.
(2) An efficient numerical optimization scheme may be further refined and implemented to calibrate the model parameters to reduce computational cost.
(3) Apply the developed Biot formulation to partially saturated soil by incorporating the third phase (gas) into the analysis.
(4) Extend the 2-D coupled finite element – infinite element numerical model to 3-D.
(5) Extend the computer program DYNSOILS to 3-D and conduct 3-D Biot analysis.
(6) Explore the possibilities to implement Quasi-Newton methods to improve the efficiency of the equilibrium convergence.
(7) It is of special interest to compare the simulation results from the computer program DYNSOILS with other commercial finite element codes, such as PLAXIS, ABACUS and so on.
(8) More numerical simulations and predictions of dynamic centrifuge experiments and prototype situations, such as shallow foundations, piled foundations and dams subjected to earthquake loading, should be performed to assess the capabilities of the developed Biot formulation.
