Two-dimensional analytical stress distribution model for unbalanced FRP composite single-lap joints

Analytical and numerical simplified modeling of a single-lap joint

“…In their study, they combined the use of Euler-Bernoulli/Timoshenko beams and the 2D elasticity theory, involving thus the three stress components (shear, peel and longitudinal stresses) which were supposed to vary along the thickness of the adhesive layer. Some of these authors [9,10] further analyzed the case of unbalanced composite SLJs and derived new expressions for the stress fields and edge moment factors, in the context of large deformations.…”

Higher order adhesive effects in composite beams

“…Spring-type models are also widely used (Benveniste and Miloh, 2001;Geymonat et al, 1999;Goland and Reissner, 1944;Hashin, 2002;Klarbring, 1991). There is a wide literature exploiting beam theories in the analysis of adhesive joints (Ascione and Mancusi, 2012;Bennati et al, 2009;Cheng et al, 1991;Goland and Reissner, 1944;Jiang et al, 2017;Kanninen, 1974;Kondo, 1995;Luo and Tong, 2004;Olsson, 1992;Qiao and Wang, 2004;Su and Gao, 2014;Whitney, 1989;Williams, 1989;Wu and Jenson, 2011;Wu and Zhao, 2013;Zou et al, 2013), just to cite a few. Other studies focus on obtaining composite beam theories via a rigorous asymptotic analysis, see e.g.…”

Theoretical solution for the axial vibration of functionally graded double-lap adhesive joints

“…Though the model is general and includes bending, shearing, hygrothermal stresses, and nonlinear adhesive behavior, the solution is calculated numerically and a closed-form solution is hard to obtain. Recently, Jiang et al [23] derived a solution for unbalanced composite double-lap joints but accounting for shear and peeling stresses. Weißgraeber et al [24] derived an analytical model for single-lap, double-lap, T, and L adhesive joints, considering plane-strain framework.…”
