Figure F2. Photograph of experimental setup of Sample 1320-31-1. Sample is mounted within a latex jacket (1). Horizontal strains are measured across four pairs of linear variable transducers (LVDTs) in a ring at sample midsection (2). Vertical strains are measured by one pair of LVDTs attached to rings spanning the central section of the sample (3). Differential stress is measured by a load cell (4) mounted above the upper platen (5). Pore fluid can be drained from either or both ends of the sample (6). Fixture used to stabilize the experimental set-up during mounting of the test, removed during testing (7).
