The quality of adhesive bond joints is characterized using acoustic methods and discussed in this paper. Acoustical images of basic types of defects in models and real industrial samples are represented. The material variety includes metal (steel, aluminium alloys, magnesium) bonded with epoxy-based structural adhesive. Three-dimensional data were obtained using an acoustic scanning microscope ...

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(2): 473–479. In this paper the mechanical behaviour of structural two-component epoxy adhesives in T-joints is experimentally investigated. The aim of this study is to analyse t...

The use of glass beams in transparent roofs and glass fins as part of the facade is already state-of-the-art construction to achieve a transparent and lightweight appearance. Until now, mechanical fasteners made from stainless steel are used to join these structural components. Those fasteners visually interfere, require holes in the glass and cause unfavorable stress peaks in the glass. In con...

From the past to present, plastic materials are used extensively in all areas of industry, thanks their shaping capabilities. Especially last 10 years, with proliferation desktop type 3D printers additive manufacturing sector, thermoplastics have become most widely material. Therewith, assembly produced by this method has gained so much importance. Since low surface energy, there difficulties p...

Peel tests are widely used to characterize the peel strength of bonded joints and control adhesion quality. There various configurations test, such as T-peel testing at 180°, floating roller climbing drum test. These methods have been mainly in aeronautical industry, a way assessing metallic joints. However, with growing use composite materials it is necessary these when subjected peeling loads...

Abstract The load-bearing capacities of (i) self-piercing-riveted, (ii) adhesive-bonded and (iii) hybrid riv-bonded lap joints commercial 1.5-mm-thick EN AW-6016-T4 sheets were compared under both quasi-static cyclic shear-tensile loads. heat-treated to cure the adhesive peak-age aluminum alloy. joint quality/integrity was assessed based on characteristic cross-sectional features hardness maps....

The tension-tension fatigue behavior of ductile adhesively-bonded double-lap FRP joints was experimentally investigated. An acrylic adhesive, which in the rubbery state at ambient temperature, provided joint ductility. degradation characterized by cyclic energy dissipation, stiffness, creep displacement and self-generated temperature. effects elevated temperature on joints’ static tensile pure ...

This report reviews predictive models suitable for evaluating long-term properties, residual strength and life expectancy of adhesive joints subjected to cyclic fatigue and/or hostile environments. Methods for simulating accelerated ageing are included in the assessment. Several different approaches, including mechanistic models, fracture mechanics, stress analysis and phenomenological models a...
