The non‐associated I 1 ‐ J 2 ‐plasticity model accounts sufficiently well for the different mechanical behaviour of crashoptimized high‐strength adhesives under combined shear and tensile loading. This model is extended to material softening due to damage, rate‐dependency and a constitutive description for the mechanical behaviour of adhesively bonded joints under compression. The material parameters are identified by means of the FE‐analysis for the experimental setup of a sample of bluntly glued double tubes. A comparison of the simulated results with the experimental data proves the validity of the model. (© 2011 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
