Description
MATLAB programs were written to extract the indentation velocity, final indentation depth, maximum pressure, average plateau pressure, rate of pressurization, and maximum force from the appropriate sensor data. Plateau pressure was not available for the cyclic indentations as there was no dwell period.
An analysis of variance (ANOVA) was performed on the peak and plateau pressures (Figure 1) to determine differences between indentation velocity and depth.
The linear region of the pressure vs. time response was extracted as the rate of pressurization.
An ANOVA was performed to determine if differences existed between the pressurization rates between the slow and fast rates.
