TL;DR: In this paper, the combined effects of temperature and humidity (termed hygrothermal) are included in a general laminated composite plate buckling theory formulation based on the Theorem of Minimum Potential Energy which accounts for transverse shear and normal deformation and the bending-extensional coupling exhibited by non-symmetrically laminated composites.

TL;DR: In this paper, the effects of introducing small grooves on the adhesive side of the adherends, perpendicular to the load direction, were examined for single lap joints under either static or fatigue loadings.
Abstract: : Recent experiments have shown that significant improvements can be made in the structural efficiency of single lap joints through several modifications Tests have been conducted in which the adherends were linearly tapered from full panel thickness to practically zero thickness over the length of the bondline in the load direction Further, tests were conducted to examine the effects of introducing small grooves on the adhesive side of the adherends, perpendicular to the load direction Similarly, grooves only over the thicker half of the tapered adherend were investigated, because these grooves do introduce stress concentrations In each case, significant improvements in joint efficiency were made under either static or fatigue loadings Additionally, specific observations are made pertaining to the residual strain effect due to joint fabrication on the fatigue life of strain effect due to joint fabrication on the fatigue life of the joint Second, studies were made on the effects of using hybrid adherends and their effect on joint efficiency
