The present-day interest in the use of composite-steel joints primary marine structures requires an in-depth knowledge fatigue performance thick adhesive joints. This paper reports on experimental tests performed compliant (i.e., and ductile) based a two-component methyl-methacrylate unaged aged conditions. Bi-material double strap joint with bondlines is subjected to quasi-static loading, duri...

Abstract The use of composite materials in structural applications has significantly expanded recent years. transport industry accounts for an increasingly larger share the final weight vehicles, as manufacturers pursue improvements fuel economy, lighter more efficient designs, and reduction emissions. However, delamination adhesively bonded joints causes premature failure bond, inhibiting its ...

The widespread use of adhesive bonded connections has been used in a range technical fields. In this paper, the interfacial stress distribution joint is presented. When determining whether or not structure dependable for operation, stresses that act along bond line an adhesively lap are utmost importance. purpose study to develop finite element solutions able anticipate shear and peel using the...

Abstract The need to manufacture lightweight structures from ultra-high-strength steels is forcing industry look for new joining technologies. Hybrid joints are one of the ways join materials. This paper investigates ultra-high strength steel plates using laser welding and adhesive bonding. Steel used in this was abrasion resistant (AR600) with tensile (Rm) ≥ 2 GPa. Three different epoxy adhesi...

To understand the effects of substrate materials on the fracture behavior of adhesive joints, experimental studies and finite element analyses have both been conducted for double-cantilever-beams (DCB) with aluminum and steel substrates at different bond thickness (h). Numerical results show that the region dominated by the crack singularity is much smaller than the bond thickness. Very small p...

A novel semi analytical method is developed for transient analysis of single-lap adhesive joints with laminated composite adherends subjected to dynamical loads. The presented approach has the capability of choosing arbitrary loadings and boundary conditions. In this model, adherends are assumed to be orthotropic plates that pursuant to the classical lamination theory. Stacking sequences can be...

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/...

Adhesive bonding is becoming increasingly common in civil infrastructure construction due to the increased use of advanced composites. Due large scale structures and their application outdoor settings, conditions during adhesive curing are substantially different from those other industries. However, little information exists on commonly used adhesives applications making design such adhesive-b...

Elements based on the exact stiffness matrix method contain an embedded analytical solution that can capture detailed local fields, enabling more efficient mesh independent finite element analysis. In the present study, this method was applied to adhesively bonded joints. The adherends were modeled as Euler-Bernoulli beams, and the adhesive layer was modeled as a bed of linear shear and normal ...
