Elastic flexural behaviour of an adhesively bonded single lap joint with functionally graded adherends

摘要: Abstract This study investigates three-dimensional elastic flexural behaviour of an adhesively bonded single lap joint with adherends composed a functionally gradient layer between pure ceramic (Al2O3) and metal (Ni) layer. The in-plane normal stress shear stresses were critical in the adhesive left free edge upper adherend–adhesive interface, right lower interface corresponding zones experience concentrations whereas middle overlap region has uniform low distribution. varies linearly through adherend thickness then becomes peak In layer, is at decreases uniformly across towards other interface. layers mechanical properties calculated based on power law. Accordingly, increasing number had minor effect through-the-thickness profiles magnitudes both addition, enriching material composition phase does not affect their ceramic-rich along interfaces increase considerably. On contrary, compositional component evidently graded joints subjected to thermal loads.
