Figure 6.
Panel a shows radial stress values ranging from about 0 to 700 kilo pascals across angles from 0 to 360 degrees and heights from 50 to 550 centimetres, with higher values concentrated near mid height regions. Panel b shows negative radial stress values ranging from about minus 330 to minus 30 kilo pascals, with lowest values around central regions and higher values towards upper sections. Panel c shows radial stress ranging from about 0 to 850 kilo pascals, with peak values near lower height regions around specific angles. Panel d shows radial stress ranging from about minus 450 to 350 kilo pascals, with lower values across central regions and higher values near lower height and higher angle positions.Change in stress and pore pressure distribution because of initial canister pressurisation. (a) Radial stress change during pressurisation (Day 5266.81), (b) radial stress change during depressurisation (Day 5277.36), (c) pore pressure change during pressurisation (Day 5266.81), and (d) pore pressure change during depressurisation (Day 5277.36)
