Stresses can be measured by X-ray diffraction, not only in metals but also in polymeric composites containing some crystalline filler particles. Diffraction is found effective in disclosing the distribution of stresses over the surface of adhesively bonded joints in aluminum strips when loads well below the yield point are applied. When two 606l-T6 aluminum strips 1/16" or l/32" thick and 3/4" ...

This paper presents new analytical model of asymmetric mixed-mode bending (MMB) specimen of adhesively bonded pultruded GFRP joints. An easily applicable relationship for the calculation of the strain energy release rate of the asymmetric MMB specimens is proposed based on the beam theory. The model is capable to analyze stacking sequence as well as various crack propagation paths. In the paper...

Carbon fiber reinforced polymers strengthen steel structural elements. These structural elements are normally subjected to static, dynamic and fatigue loadings during their life-time. CFRP laminate is commonly used structures under the subjected loads. A number of focused on the characteristics of CFRP sheets members under static, dynamic and fatigue loadings. is a gap in understanding the bond...

Strength and failure analyses are critical to the safe sustainable design of any structure. In case adhesively bonded joints, particular attention must be paid adhesive layer, which is comparably compliant subject high stresses. Determining stresses in layer essential identify areas joint prevent formation cracks. most applications, joints have thin layers that can already accounted for with hi...

The application of adhesive bonding technology in aircraft structures can reduce the total wight greatly, but bonded joints are very sensitive to possible manufacturing defects and damages during service operations, which makes them difficult meet damage tolerance requirements current transport airplane structures. In this study, composite-metal hybrid reinforced by multiple penetrative thin pi...
