This paper proposes a new lap-joint configuration, the so-called Orion beam. The setup is composed of two thin beams connected by three bolted joints with contact patches on each connecting bolt. beam suggests an assembly in which there are bolts dedicated to “static” functions guarantee structural integrity and those that perform “damping” increase energy dissipation due frictional contact. In...

Structures joined by lap-joints can present complex nonlinear dynamic behavior as a function of the stress to which lap-joint is subjected, including contact stiffness variations and softening, along with hysteresis effects related frictional dissipation at interface. Considering applications where use non-parametric models that depend only on input output data required, this work proposes deta...

Stresses in single-lap bolted joints of thick plates are complex and difficult to analyze. The few previous studies of stress through the thickness of bolted joints have been limited to finite element simulations and have been implemented only for the joining of relatively thin plates. Experimental and numerical analyses were conducted to analyze the stress distribution inside thick bolted plat...

This paper presents the application of a new method for interfacial modeling utilizing a merger of continuous Galerkin and discontinuous Galerkin concepts to simulate the behavior of mechanical joints. The interfacial flux terms arising naturally from the discontinuous Galerkin treatment provide a mechanism to embed friction models in a variationally consistent fashion. Due to the unbiased impl...

in this research, the influence of bolt preload on the fatigue strength of 2024-t3 aluminium alloy double lap bolted joints has been studied experimentally and numerically. to do so, three sets of the specimens were prepared and each of them subjected to tightening torque of 1,2.5 and 5 n-m and then fatigue tests were conducted under various cyclic axial load levels. in the numerical method, th...
