Abstrakt: Adhesive bonded joints are extensively used in the aerospace sector as compared to other joining techniques. In this paper, experimental and numerical analysis of single lap-jointed samples has been carried out with two different adherents such as Al-Al and Carbon fiber reinforced polymer(CFRP-CFRP). The shear strength of AV138/HY998 adhesive is estimated with Al-Al adherents and CFRP-CFRP adherents. Further, the adhesive fracture toughness is estimated experimentally and numerically. To estimate mode I fracture toughness double cantilever specimens are made as per the standards and tested under tensile load. The opening mode fracture toughness is estimated using simple beam theory and the Virtual crack closure (VCCT) technique. [ABSTRACT FROM AUTHOR]
