Abstract: An adhesive-based joint (100/300) includes a first adherend (110), a second adherend (120), an adhesive layer (130) located between the first adherend (110) and the second adherend (120), and plural strip parts (144) of a low adhesive material embedded into the adhesive layer (130). The low adhesive material has an adhesion with the adhesive layer (130) lower than an adhesion between the first or second adherend and the adhesive layer.
