Prediction of debonding strength of tensile steel/CFRP joints using fracture mechanics and stress based criteria

A nonlinear theory for CFRP strengthened aluminum beam

“…As indicated by Bocciarelli et al [7], under externally applied tensile load, N, the shear stress, s a1 , close to the reinforcement end is given by…”

Interfacial fracture criteria based on the nominal deformation energy of interface

“…Interfacial failure includes the fracture induced by an interface crack (the problem of interfacial toughness) and the debonding of a perfect interface induced by interfacial stresses (the problem of interfacial strength) [1][2][3][4][5][6][7]. There are a huge amount of studies on interface crack [8][9][10][11][12].…”

Failure stress criterion for adhesively bonded joint at different strain rates by using dynamic Arcan test device

“…For the stress based criteria, the maximum principal stress is mainly used for very brittle materials [1,2] (since cracks initiate and propagate in a direction normal to these maximum principal stresses). Shear stress has also been extensively used to predict lap joint strength [3].…”
