Method analyzes analogue plots of paperboard stress-strain data*

KEYWORDS One of the most important properties of paperboard is characterized by the Stress-strain properties analogue plot of stress vs. strain obtained from an edgewise compression Paperboards loading test. A method is given for determining the average stress-strain Compression tests curve for a group of curves by the use of representative models. An approximate method also allows data be read from a stress-strain curve so the analysis can be performed with a hand calculator.
