A wide variety of adhesive joints architectures is available, offering several options to the designers, although most common are single-lap (SLJ), double-lap joints, and scarf joints. Additional designs, less used studied stepped-lap, T-joints tubular find application in different types industry, such as aircraft bond stiffeners skin cars between B-pillar rocker. This work numerically evaluate...
Novel techniques for joining thermoplastic composites and aluminium alloys are critical underpinning the development of crashworthy lightweight multi-material automotive structures. Lap bonding interfaces represent a fundamental joint in typical This study investigates crashworthiness single-lap, adhesively bonded interlocked-hybrid composite-metal joints using low-velocity transverse impact te...
For adhesively bonded joint security and long-term use of the joint, a precise stress analysis must be performed on single-lap joints. A formed by joining two layers at given lap length, is most widely used adhesive type in practice. Nowadays, it stated that mechanical properties strength can increased adding clay graphite to polymeric material joints, trying estimate for various loading condit...
Abstract Glass/steel adhesive joints are being used increasingly in the construction industry as they offer significant structural advantages over conventional mechanical fastener approaches. However, also known to be sensitive moisture diffusion into bondline, which reduces interfacial bonding strength for hybrid glass/steel substrates. The effect of on performance degradation has been success...
Composite bonded structure is a prevalent portion of today’s aircraft structure. Adequate bond integrity critical aspect fabrication and service, especially since many structural bonds are for flight safety. Over the last decade, non-destructive evaluation techniques have improved but still cannot detect structurally weak that exhibits full adherend/adhesive contact. The result expensive time-c...
Bonded joints used in wing sections and frames of aircraft structures are mostly exposed to cyclic loadings instead static ones during their services. Bending types dynamic encountered. In this study, the fatigue response a single lap joint (SLJ) bending loading was studied with developed advanced finite-element (FE) model. The cohesive zone model describing behaviour adhesive layer damage mech...
This paper proposes a new lap-joint configuration, the so-called Orion beam. The setup is composed of two thin beams connected by three bolted joints with contact patches on each connecting bolt. beam suggests an assembly in which there are bolts dedicated to “static” functions guarantee structural integrity and those that perform “damping” increase energy dissipation due frictional contact. In...
This paper studies the lap shear, in which both adhesive and adherends are elastic, but is much softer than adherends. The shear lag model identifies a length, called length Ls. energy release rate of debond crack affected by elasticity Their relative importance characterized ratio remaining joint, L, to In short-joint limit, L/Ls→0, do not deform, gives rate. long-joint L/Ls→∞, interior does a...
