Analysis of Notched Newsprint Sheet in Mode I Fracture

På svenska

Author

Summary, in English

A new approach to analyze notched paper sheet loaded in mode I, based on cohesive crack modelling, is investigated. The method predicts final failure of the sheet, regardless of the sheet size and initial crack length. Onset of crack growth, stable crack growth and onset of unstable crack growth are predicted. The simulations of the notched paper sheet reveal that the concept of autonomy, i.e. independence of specimen geometry and load configuration, in a region near the crack edge does not in general prevail, except at small-scale yielding. The

method is confirmed by a large number of experimental tests. Different sheet sizes are tested. In the experiments, 45 g/m2 newsprint was

used.
