Abstract

Efficient use of paper products involves using modern aspects of materials science and engineering mechanics. This implies the ability to determine simultaneously different components of strain at multiple locations and under static or dynamic conditions. Although measuring strains in paper has been a topic of interest for over 40 years, present capability remains limited to recording strain in a single direction and over gauge lengths exceeding 20 mm. Improved full-field methods are needed. Of several possible optical techniques, moiré demonstrates potential for full-field analysis of paperboard.
