Abstract
Tensile lap shear tests at various temperature were performed at several crosshead speeds using single-lap joint specimens. In the tensile lap shear tests, it was found that the strength of the adhesive is highly temperature-sensitive. In the present work, the effect of forming temperature on the deformation characteristics of adhesively bonded aluminum sheets was investigated by performing V-bending experiments with various temperature. In order to discuss the effect quantitatively, the numerical simulations for the bending were also conducted using a rate and temperature dependent constitutive model for the adhesive. Consequently, it was found that the large shear deformation and 'gull-wing' bend are suppressed by low temperature forming.
