Combined tension-torsion experiments of an adhesively bonded butt-joint were performed using a highly ductile acrylic adhesive. From the experiments, it was found that the multi-axial flow stresses and fracture limits are strongly dependent on shear strain rate and stress multiaxiality. The multi-axial flow stresses are calculated with an extended version of the present authors'constitutive model, and they are compared with the corresponding experimental data Furthermore, fracture limit curves expressed in the normal and shear stress plane is discussed based on the experimental data and the numerical predictions.
