On Material Characterization of Paper Coating Materials by Microindentation Testing

摘要

Microindentation as a method for determining important material properties of paper coating materials is studied experimentally and numerically.The bulk of the investigation is concentrated upon the short-lived elastic part of a spherical indentation test,but determination of the failure stress of the coating is also discussed.The results indicate that mi-croindentation can be a powerful tool for material characterization of these materials,but only if careful efforts are made to account for the influence from plasticity as well as from boundary effects.
