Figure 14. Compression Testing Vent Hole The data from the compression tester was exported to an Excel file for analysis. The crushing yield load, deflection at crushing yield load, and apparent crushing stiffness were extrapolated from the data as follows: Crushing Yield Load – Point on the crush load/deflection curve at which an increase in deflection occurs without an increase in crush load expressed in lbs. to three significant figures (Figure 15). Deflection at Crushing Yield Load – Reduction in height (x-axis of Figure 15) of the sample at the crushing yield load expressed in inches to three significant figures. Apparent Crushing Stiffness – Calculated by selecting a point on the straight line segment of the crush load/deflection curve as shown in Figure 15 and dividing force at this point by the corresponding deflection expressed in pounds per inch to three significant figures. 30
