This paper deals with the temperature-dependent elasto-viscoplasticity behaviour of a highly ductile acrylic adhesive and its effect on plastic bending of adhesively bonded sheet metals . Tensile lap shear tests of aluminium single-lap joints were performed at various temperature of 10-40℃ at several tensile speeds. Based on the experimental results , a new constitutive model of temperaturedependent elasto-viscoplasticity of the adhesive is presented . From V-bending experiments and the
