Figure 1.
The image depicts a vertical experimental apparatus designed for material testing, featuring a cylindrical tank with a broad base and a narrower upper section. At the top, an electric actuator is mounted on a loading frame, positioned above the tank. The cylindrical unit includes several labelled components, such as a Rigid cap, Sample former, Anchoring unit, and Loading plate. Inside the tank, a Membrane and a Pneumatic cushion are shown, with Cell pressure indicated as a function of the system. The tank dimensions include measurements of 670 millimetres and 730 millimetres. The background illustrates equipment settings such as monitors and wiring, indicating a laboratory environment for conducting experiments.Outline of the developed calibration chamber: photo (left) and schematic cross-section (right)
