The analytical model results in simple equations, suitable for immediate design use. The load-deflection curve of a plated beam, from the onset of debonding up to the complete separation of the plate, is obtained by controlling the length of the interfacial debonding crack. Its shape clearly shows that snap-back or snap-through instabilities may arise when the beam is loaded under displacement or force control. Analytical predictions are also compared with finite element results based on an interfacial cohesive crack model. It is shown that the predictions of the proposed analytical model match closely the numerical solution, provided that an effective crack length accounting for the size of the fracture process zone is used in the calculations. date: 2010 publication: Advances in Structural Engineering volume: 13 number: 5 publisher: Multi-Science Publishing pagerange: 875-889 id_number: doi:10.1260/1369-4332.13.5.875 refereed: TRUE issn: 1369-4332 official_url: http://dx.doi.org/10.1260/1369-4332.13.5.875 citation: Zavarise, Giorgio and Carpinteri, Alberto and Paggi, Marco and De Lorenzis, Laura Technical Papers: Linear elastic fracture mechanics approach to plate end debonding in rectilinear and curved plated beams.
