In the plot in Figure 7, the peak load (Y-axis) indicates the tablet hardness; harder tablets will give a higher peak load. The distance to peak load (X-axis) is an indication of the elasticity of the test sample. Brittle samples (such as solid-dose tablets) will have a shorter distance or time at failure hardness compared to elastic samples.
