International audience; The present article proposes a simple analytical method to describe the behaviour, under alternating tensile loading (R=0), of a hybrid load transfer bolted joint assembly, that is working both with adhesion and plastic deformation-shearing. It is shown that apparent flexibility can be defined as depending on the pre-stressing applied and the type of calculation you wish to perform. Application to calculating the distribution of loads transferred between the different rows of fasteners of a bolted joint assembly is then covered. It is thus shown that the rate of transfer on the first row increases strongly with pre-tightening of the screws. Application to an aeronautical assembly with four rows of fasteners is introduced. Comparison of the results obtained by extensometric measurements, by simulations using finite elements and by analytical calculation shows that the analytic modelʼs precision is quite satisfactory for use in pre-sizing.
