Current renewed interests on adhesive bonding is driven by need for improved BIW performances. It was pointed out adhesive bonding particular property to provide an optimal mechanical work of a given conception (drawing) with related stiffness, NVH and fatigue behaviour improvement. Combined to the fact that it well accommodates with classical spot welded design (contrary to laser welding where specific drawing is required, more impacting on engineering practices) and to its industrial process high productivity; its real implementation in automotive industry and its generalisation to all segments is now expected. Even if structural bonding is often said to be an old technology in the automotive field (indeed NISSAN pioneer massive application dated from 1960's), few really structural applications have ever been developed. The use of adhesive strength potential, even inherent to structural bonding mechanical normal definition, constitute a technical stake of another order. Renault voluntary demarch aims at challenging it to provide new cost-efficient solutions for safety improvement and weight reduction. It requires an effective mastering of structural bonding technology, i.e. the capacity to perform a systematic and secure use of its promising strength potential, where 'edge effect' modelling problem naturally appears, and ageing problem takes a really crucial importance. Renault R&D guideline, in front of adhesive strength modelling problem 'obviously' postulate that developed tools must be operational in engineering development project, what singularly complicate resolution of this mechanical problem and drive the need for new calculation approach (to some extend solely initiated with asymptotic expansion method based tools). Promising modelling results for structural bonding crash reinforcement on industrial sub system have been presented. Regarding ageing problem, often considered as a blocking point in structural bonding development, it has been pointed out that, from the automotive point of view, problem firstly stands in capacity to integrate this phenomenon in the design rather than in development of new more accurate ageing test.
