Experimental characterization and modelling of adhesive bonded joints under static and non-monotonic fracture loading in the mode II regime

Understanding and predicting the behaviour of bonded joints under different loading conditions is certainly an aspect primary importance. Although numerous experimental studies have been carried out over last few decades, shear cyclic has not investigated in detail. To fill this gap, extensive numerical program double lap out. The were tested static to evaluate compare influence external forces on adhesive performance. results are discussed terms force-displacement relationship, stress, stiffness, residual displacement, initial damage. Finally, a method presented for actual using imperfect interface model with damage evolution. good agreement all conditions. This work provided validated interesting design tool structures.
