TL;DR: In this paper, the interfacial shear strength between epoxy and carbon fibers, measured from microdroplet specimens adhered onto a single carbon fiber, was analyzed using finite element analysis of the droplet, sphere and cylinder model types.

TL;DR: In this paper, a multiscale approach to composite failure, in which detailed information on small-scale micromechanics is incorporated approximately yet accurately into larger-scale models capable of simulating extensive damage evolution and ultimate failure, is applied to the deformation and failure of a Ti-matrix composite.

TL;DR: In this paper, the authors compared the tensile and fatigue properties of wrought aluminum alloy 2198-T351 and Alloy Alloy 2024-T3 that is currently used in aerostructures and found that the latter was superior in the high cycle fatigue and fatigue endurance limit regimes, especially when considering specific mechanical properties.

TL;DR: In this paper, an adhesively bonded lap joint is analyzed by assuming that the adherends are elastic and the adhesive is linearly viscoelastic, and the standard Laplace transform technique is used to solve the problem.
Abstract: In this paper an adhesively bonded lap joint is analyzed by assuming that the adherends are elastic and the adhesive is linearly viscoelastic. After formulating the general problem a specific example for two identical adherends bonded through a three parameter viscoelastic solid adhesive is considered. The standard Laplace transform technique is used to solve the problem. The stress distribution in the adhesive layer is calculated for three different external loads namely, membrane loading, bending, and transverse shear loading. The results indicate that the peak value of the normal stress in the adhesive is not only consistently higher than the corresponding shear stress but also decays slower.
