- Abstract
A new approach to justify the dependence of microhardness of semicrystal-line polymers, specially polyethylene, upon average crystal thickness is given. A basic model of deformation under local compression is proposed in terms of the heat dissipated by the plastically deformed crystals and the volume of crystals destroyed under the indenter. The results indicate that the mechanism of deformation is dictated by the initial mosaic-block structure controlling the generation of a final system of shear planes. Though the analysis is approximate, acceptable parameters give satisfactory agreement with observation.
