The peeling force–displacement evolution law that characterises the delamination of micromechanical double cantilever beam specimens of paper tissue have been extracted from such peeling tests. It is observed that the force–displacement evolution curve achieves a steady-state value related to the effective adhesive energy of the interface. This behaviour is explained by examining the complex load transfer mechanism between the layers exerted by cellulose fibrils. A statistical approach is used for the computation of the effective adhesive energy. It is argued that the observed force–displacement evolution law may be satisfactory described by a stochastic model that depends on the distribution function of the fibrils strength, and on two geometrical distribution functions related to the in-plane and out-of-plane fibrils angles with respect to the undeformed interface configuration. Some applications of the proposed model are demonstrated on examples. date: 2016-05-09 date_type: published publication: Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science volume: 230 number: 9 publisher: Sage pagerange: 1440-1448 id_number: 10.1177/0954406215612502 refereed: TRUE issn: 0954-4062 related_url_url: http://dx.doi.org/10.1177/0954406215612502 related_url_type: pub funders: European Research Council projects: ERC StG CA2PVM 306622 citation: Borri, Claudia and Paggi, Marco and Reinoso, José and Borodich, Feodor M Adhesive behaviour of bonded paper layers: Mechanical testing and statistical modelling.
