Data reduction is usually based on the assumptions of Linear Elastic Fracture Mechanics, which are not fulfilled in configurations involving large scale fracture, such as in adhesive joints. In this work, a J-integral-based method that can be applied in presence of large fracture process zones is presented. The proposed method requires less input information and avoids crack length monitoring during the test, which reduces the uncertainty of the results as compared to traditional methods. The method is shown to accurately compute the fracture toughness in a delamination test campaign and to provide results with lower uncertainty than those of the ASTM standard method The authors also acknowledge the support of the Spanish government through the Ministerio de Economía y Competitividad under the contracts DPI2012-34465 and MAT2012-37552-C03-03 http://hdl.handle.net/10256/13731 Adhesius Adhesives Mecànica de fractura Fracture mechanics Assaigs de materials Materials -- Testing Resistència de materials Strength of materials An experimental data reduction method for the Mixed Mode Bending test based on the J-integral approach
