Figure 4
The two compression testing systems are used for the mechanical characterisation of specimens under different loading conditions. Panel A presents a quasi-static testing arrangement using an M T S machine with labelled components including Crosshead, Load frame columns, Load cell, Upper platen, Specimen, Laser extensometer, Lower platen, and Digital camera. A corresponding experimental setup photograph is shown beside the schematic. Panel B illustrates a dynamic testing arrangement using an Instron V H S system equipped with a high-speed camera and a data acquisition system. Labels identify the Crosshead, Load frame columns, Load cell, Upper platen, Specimen, and Lower platen. Experimental photographs accompany both schematics to demonstrate the physical testing configurations.Schematic and experimental compressive test setups: (a) quasi-static test and (b) dynamic test. The images on the left are sketches, while the images on the right are photographs
