| The subject of this study is aluminum box beams of omega cross-section, consisting of an omega profile and connected to the metal by the adhesive interface of the area 120 cm2. In the laboratory tests were used specimens made from 7075 aluminum with dimensions 300 x 84 x 36 mm. To connect the components of the specimens an adhesive layer Loctite 9545 was used. The samples were subjected to 3-point bending (3-PB). Laboratory tests were conducted using a MTS (25kN) and a Digital Image Correlation (DIC) system, in order to accurately determine states of deformation of the box beams. With the load increase the profiles deform elastically at the beginning and then in the final stage of deformation process, a collapse of the side walls and local plastic deformation occured. This causes a sudden drop of the load capacity of the entire profile. To complete the experimental analysis, the numerical model of the thin-walled box beam was created. The model allows for observation of stress and displacement fields variation in the bending element, as well as places of their concentration. Moreover, a detailed analysis of damage growth and the final destruction of the connecting elements associated with the load increase was performed. Numerical simulations were done using ABAQUS code. The FEM analysis results confirm correctness of the assumptions in the numerical model and allow for a more detailed description of the process decohesion adhesive layer and the damage of aluminium elements of the thin-walled box beams. |
