Page Comparison

Force versus crosshead displacement, force versus deflection data continuously, or at frequent intervals (around 2-3 recordings per second, with a target minimum of 100 recorded data points)

If there are any initial failures, record force, displacement and mode of damage where the failure occurs. 

Record mode, area and location of each failure. 

Use the failure identification codes, shown in the figure below.

Record the max force, failure force, head displacement and the deflection at the moment of ultimate failure. 

For ultimate failure modes, record the mode, area and location of ultimate failure for each material.
