Annotation

The technique of an estimation of local deformation under uniaxial tension at a constant rate applied to sheet pulp and paper materials is presented. Experimentally established that in inhomogeneous structure of cellulose fiber material the presence of heterogeneity of the longitudinal and transverse tensile local deformations and their quantitative and statistical evaluation is given. Provides a method for visual representation of the field local deformations. Experimentally confirmed that the sample breaks in the region of the maximum heterogeneity of local deformations.
