Abstract In this study, the joint strengths of single-lap bolted and bolted/bonded (hybrid) joints formed by using four different engineering plastics were experimentally investigated. High-density polyethylene (HDPE), ultra-high molecular weight polyethylene, Delrin (POM), Teflon used as plate materials in connections. Standard M6 bolts bolt The specimens prepared single bolted, double bolted/...

The use of structural adhesives in automotive industry is increasing steadily, as manufacturers become aware of the advantages that adhesives can offer, compared with the conventional techniques. However, not only the adhesive properties must be analyzed, the geometry must be taken into account as well 1 . It is theoretically and experimentally proved that, adhesive joints are more reliable tha...

Adhesively bonded structures are potentially lighter in weight than mechanically fastened ones, but existing surface treatments are often considered unreliable. Two main problems in achieving reproducible and durable adhesive bonds are surface contamination and variability in standard surface preparation techniques. In this work three surface pretreatments were compared: laser etching with and ...

Modal analyses are essential steps in structural design. Simple and quick numerical procedures design tools for modal dynamic analysis of bonded joints would be an attractive option to increase the efficiency process its early phases. This paper offers a simple tool dedicated single lap with balanced unbalanced adherends various boundary conditions. Based on macro-element technique developed Ta...
