Investigating the influence of material non-linearity in the fracture properties of ductile adhesives submitted to mixed-mode loading

The influence of the mechanical behaviour of a crash optimized adhesive in its fracture properties at different mode ratios in the plane I/II is discussed. The adhesive under investigation has been previously studied by means of standardized TDCB (Tapered Double Cantilever Beam) and MMB (Mixed Mode Bending) tests. In the current study, these tests were modelled numerically considering first the linear elastic case for the adhesive and secondly...
