The transverse and longitudinal elastic constants of pulp fibers in paper sheets

Abstract Cellulose fibers are a major industrial input, but due to their irregular shape and anisotropic material response, accurate material characterization is difficult. Single fiber tensile testing is the most popular way to estimate the material properties of individual fibers. However, such te...
