... between the buffer and the surrounding cementitious members are considered as rigid boundaries (sharing nodes) basically (Basic analysis is described in Chapter 4). Additional analyses (in Chapter 5) are conducted as more realistic condition because local tensile stresses are found in the buffer during...

... for UCS test simulation is shown in Figure 4(a). Figures 4 (bd) illustrate the minimum principal stress built-up and corresponding rock failure process. In these figures also, compressive stress is shown as negative (cold colour) and tensile stress is regarded as positive (warm colour). Figure 4(b...
