Through-Thickness Load Transfer in Adhesively Bonded Composite Joints

Assessment of local strain field in adhesive layer of an unsymmetrically repaired CFRP panel using digital image correlation

“…They studied the influence of adhesive ductility on joint strength and strain distribution at the overlap ends and concluded that the adhesive with relatively low tensile strength and high ductility provides a higher joint strength. Crammond et al [24] have used full-field measurement techniques to analyze the complex stress and strain distributions in adhesively bonded composite joints using thermoelastic stress analysis (TSA) and DIC. The experimental stress and strain data in their study is manipulated to give the same output for the purpose of comparison and a reasonable agreement between the two independent measurement techniques is achieved.…”

“…A detailed review on numerical modeling of adhesively bonded joints is presented by da Silva and Campilho [8] and He [9]. To validate the numerical predictions researchers have used several experimental techniques such as strain gauges [10][11][12], moiré interferometry [10,13], photoelasticity [14] and digital image correlation (DIC) [15][16][17][18][19][20][21][22][23][24][25]. DIC has been used extensively in recent years because of its advantages over the other experimental technique [22,[26][27][28].…”

Critical analysis of adhesive layer behavior in patch-repaired carbon fiber-reinforced polymer panel involving digital image correlation

“…[10][11][12][13] Recently, researchers have used DIC for understanding the behavior of adhesively bonded joint. [13][14][15][16][17][18][19][20][21][22] Comer et al 13 have used both 2D and 3D DIC technique to study the evolution of deformation and strain in composite single lap-bonded joints prior to failure. Colavito et al 14 have used DIC technique to measure displacement and strain field within the adhesive layer of adhesively bonded double-lap joint.…”

“…They have also investigated the effect of influence of adhesive ductility on the joint strength. Crammond et al 21 have used full-field measurement techniques to analyze the complex stress and strain distributions in adhesively bonded composite joints using thermoelastic stress analysis and DIC. Kumar et al 22 have presented an experimental approach of measuring the strains in the adhesive bondline of composite single-lap joints using DIC.…”
