Real-time visual analyses on failure criteria of slope stability in strength reduction finite element method
The failure criteria in strength reduction FEM are not unified and often affected greatly by researchers experience and judgment,so it is necessary to discuss the applicability and the difference of some various criteria of instability of slope.According to the thought of visualization in real time computing,the corresponding visual program is developed based on some common failure criteria adopted simultaneity in the strength reduction FEM.Then,through the real-time visual interface,the comparisons of the common failure criteria are conducted.The results show that,the safety factor of a simple slope can be determined clearly from the inflection point of the computational curve based on the criterion of the characteristic nodal displacement and the criterion of equivalent plastic strain exceeding a certain value,by contrast,the safety factor which based on the criterion of the iteration non-convergence lag behind the others in the same condition.
