The ductility of the adhesive layer in shear is the key property affecting the joint strength; the reference parameter is the ultimate adhesive shear strain energy, which is proportional to the toughness given by the area under the stresstrain curve (Hart-Smith, 1973a).In addition, ductility offsets the effect of shear and peel stress peaks. The shear stresstrain response
The current study introduces a method for manufacturing steelluminum bearing bushings by compound forging.
