The effects of uncertainties on the strength of a single lap shear joint are explained. Probabilistic and possibilistic methods are used to account for uncertainties. Linear and geometrically nonlinear finite element analyses are used in the studies. To evaluate the strength of the joint, fracture in the adhesive and material strength failure in the strap are considered. The study shows that li...

Adhesive lap joints are widely used in modern structures. Known analytical mathematical models of the stress state describe straight beams or cylindrical coaxial pipes. It is assumed that these structures depends on only one coordinate. The study plates with defects, which reinforced by patches, most cases requires use at least two-dimensional models. In this work, it shown axial symmetry plate...

The present research studied the acoustic properties of 40 oak timber samples (Quercus castaneifolia): the acoustic coefficient (K) and acoustic conversion efficiency (ACE) in free vibration mode, using the free-free bar method with different planes of vibration, i.e., tangential (LT) and radial (LR). These acoustic parameters were considered for both primary virgin wooden beams and modified be...

In this work, the effect of adherend shape on the tensile strength of adhesively bonded single lap aluminum structures joint was numerically studied using three dimensional finite element models. Six joint models were investigated. In this paper, a static finite element analysis was performed in A...

Adhesive bonding of polymer matrix composites offers various advantages over traditional fasteners, such as a uniform stress state, reduced weight, and delay composite delamination. However, adhesive has limited implementation due to challenges in the prediction durability. This work introduces new method monitor an adhesively bonded joint by dispersing magneto-electric nanoparticles (MENs) int...

In this paper, an experimental study concerning the effect of surface morphology on mechanical properties of adhesive bonding behaviour of continuous carbon fibres reinforced PEEK was performed. Surface morphology of PEEK composite was varied by sandblasting process. 3D morphological parameters were calculated from interferometry measurements. Surface wettability behaviour was studied by depose...

In this work an advanced analytical model for the efficient prediction of stress distributions in adhesive layer bonded joints is presented. order to better account local deformation effects occurring thicker layers, a quadratic-extended displacement approach introduced. The use general sandwich-type overlap region enables wide applicability analysis different joint shapes and load cases.
