Determination of bilinear elastic-plastic models for an acrylic adhesive using the adhesively bonded 3-point bending specimen

The adhesively bonded 3-point bending specimen was employed for obtaining bilinear elastic-plastic approximations to the shear stress-strain behaviour of a common acrylic adhesive. The parameters of those approximations were quickly obtained from two simplified versions of a previously developed beam model. The latter predicted fairly accurately the experimental load-displacement curves. The shear strain distributions predicted were also in...
