The development of new adhesives has allowed to expand the application bonding into most diverse industrial fields. This review article presents commonly used experimental methods for investigation mechanical performance adhesively bonded joints in aerospace, wind energy, automotive and civil engineering sectors. In these sectors, due their excellent intrinsic properties, composite materials are often along with conventional such as steel, concrete aluminium. this context, limitations that...
Mechanical metamaterials with engineered failure properties typically rely on periodic unit cell geometries or bespoke microstructures to achieve their unique properties. We demonstrate that intelligent use of disorder in leads distributed damage during failure, resulting enhanced fracture toughness minimal losses strength. Toughness depends the level disorder, not a specific geometry, and confined lattices studied exhibit maximum enhancement at an optimal disorder. A mechanics model relates...
The aim of this study is to investigate the effect adherend material on mode I fracture behaviour bi-material composite bonded joints. Both single-material (steel-steel and composite-composite) (steel-composite) joints with a structural epoxy adhesive are studied. Additionally, two bondline thicknesses considered: 0.4 mm (thin bondline) 10.1 (thick bondline). Penado-Kanninen reduction scheme applied evaluate strain energy release rate. results show that energy, GIc, independent type joint...
Thicker bondlines along with manufacturing-tolerant and fracture-resistant adhesives are trends visible across different industries, especially maritime. In this work, two contrasting adhesives: an elastic-brittle epoxy-based, a nonlinear-ductile methyl methacrylate (MMA) characterized compared via tensile, compact tension (CT) double cantilever beam (DCB) testing, for steel-to-steel adherends. Significant differences captured between the bonding materials in terms of energy required crack...
The modelling of heterogeneous and architected materials poses a significant challenge, demanding advanced homogenisation techniques. However, the complexity this task can be considerably simplified through application micropolar elasticity. Conversely, elastic foundation theory is widely employed in fracture mechanics analysis delamination propagation composite materials. This study aims to amalgamate these two frameworks, enhancing accommodate exhibiting behaviour. Specifically, we present...
Abstract Wedge tests are usually analysed assuming that the free, unbonded members may be treated as encastré cantilever beams. However, if adhesive layer is sufficiently flexible (e. g., due to low elastic modulus), then significant strain in bonded region occur and lead modification of behaviour outside this region. Using conjunction a sensitive gauge method on asymmetric wedge mathematical analysis developed from work Winkler, we conclude standard, simple beam theory approach...
The subject of mechanical metamaterials has been gaining significant attention, however, their widespread application is still halted. Such materials are usually considered as stand-alone, vis-\`a-vis all characteristic length scales being associated solely with geometry material itself. In this work we propose novel interface regions joining two potential replacing bulk adhesives. This idea leads into paradigm shifts for both and adhesive joints. specific, outline methodology testing...
This study investigates the fracture onset and crack deflection in multi-material adhesive joints with thick bond-lines (≈10 mm) under global mode I loading. The role of adherend-adhesive modulus-mismatch pre-crack length are scrutinized. parameters controlling path directional stability also discussed. Single-material (i.e. steel-steel GFRP-GFRP) bi-material steel-GFRP) double-cantilever beam bonded a structural epoxy tested. modelled analytically, considering on elastic-plastic foundation,...
Macro and microstructural damage was studied in typical glass fibre-reinforced polymer laminates with two types of coating systems – (a) isophtalic gel coat: pure or mixed SiO 2 nanoparticles 5 wt% (5%N) 10 (10%N) (b) a two-layer system: urethane-modified vinyl ester-based coat additional polyester barrier layer. Accelerated tests were performed at 50℃ for 50 days specimens nanoparticle-modified the without coat. Long-term ageing behaviour 23℃ assessed systems. Nanoparticle-reinforced (10%)...
The demand for composite materials is higher than ever before. Effective and reliable modelling techniques allowing better understanding of their failure are critical designing future optimised light-weight structures. However, at the microscopic level a complex phenomenon it has often been analysed using empirical approaches. A promising alternative, that instead takes physics-based approach, phase-field model (PFM). This approach applied comprehensively to homogeneous briefly extended...
Material architecture provides an opportunity to alter and control the fracture process zone shape volume by redistributing local stresses at a crack tip. Properly designed structures can enlarge plastic enhance effective toughness. Here, we use pillar array as model structure demonstrate how variations in geometry tip size of be used engineer Elastic–plastic finite element simulations are show width, spacing, height varied tailor zone. A set analytical mechanics models that accurately...
