Abstract
Airframe developments use composite components extensively; bonding, as a rivetless assembly solution, is thus gaining in importance, leading to the need for accurate characterization of adhesive behaviour and the development of adapted models. Structural adhesives often show large inelastic behaviour before failure [1]; however the modelling of the 3D elasto-plastic behaviour of adhesives is not straightforward. Indeed, advanced models taking into account the hydrostatic pressure dependency and defined under a non-associated formalism ([1- 4]) are needed for an accurate description of adhesive materials under a wide range of loads covering tension, shear, mixed tension/compression-shear loads. This study presents the assessment of two non-associated elasto-plastic models: the Exponent Drucker-Prager model, and the Mahnken-Schlimmer model [3], using a large experimental database obtained with a modified Arcan apparatus [5] on a structural adhesive. The aim is to develop a reliable numerical model in order to obtain good numerical predictions of the real behaviour of complex industrial type bonded assemblies.
