Mechanical behavior of wood-plastic composites investigated by 3D digital image correlation

Résumé

The tensile behavior of wood-plastic composite (WPC) with or without additive is studied using full-field strain measurements by 3D digital image correlation. It is shown that macroscopic values of the longitudinal strain are close to those measured by mechanical extensometer using standard mechanical tests. The modulus of elasticity provided by a Maxwell-Bingham model fitted to the experimental tensile curves is analyzed for several WPC formulations depending on the wood contents and the presence of additive. Color maps of the spatial strain distribution are commented. Moreover, the damage behavior and the degree of heterogeneity are analyzed thanks to the spatial standard deviation of the longitudinal strain field.
