back to the future摘要：Recent rearch efforts in the automotive industry have been focud on the integration of high-strength steels within lightweight vehicles by using improved joining techniques. The prent work falls in this subject area and is focud on the analysis of adhesive bonded dual-pha steel/epoxy joints for the automotive industry. Two quasi-static loadcas were considered, i.e. single-lap and T-peel tests, and various surface preparation strategies were evaluated. In particular, the mating surfaces were pre-treated by using puld lar irradiation with a fiber lar (1064nm) and comparisons were made with degreasing and sand blasting. Moreover, the effects of bondline thickness and adhesive type were also assd. To this aim, two epoxy adhesives with fairly different mechanical behavior (i.e. strain hardening versus elasto-plastic)...
