摘要
The ring crush (RC) test and the short-span compression (STFI) test can be used to evaluate the compression strength of corrugated board components, and can be correlated with combined board strength. Because each test evaluates paper strength at a different length scale, the correlations are not of equal quality. We find that the RC test correlates better with ECT strength of corrugated board, even when only a few RC specimens are used to evaluate the RC strength of the paper, and even when variations due to multiple combining sites are included in the analysis. We can relate the difference in correlation to the difference in failure mechanism within each paper test in relationship to the failure length scales in combined board.
