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 study, the effect of tool pin length on friction stir lap welding 430 and 304 stainless steels has been investigated. The thermal history interface was measured by thermocouple. interfacial macro- micro-structures under different lengths were analyzed via optical microscope scanning electron microscope. Also, tensile shear tests carried out to evaluate strength joint. results show that ...

This paper presents a study of moisture absorption-desorption effects in single lap adhesive joints. Experiments were carried out to characterise the moisture uptake of the single part epoxide adhesive, FM73. Tensile testing of single lap joints manufactured from aluminium alloy 2024 T3 and O and FM73 adhesive was carried out after the joints were exposed to different conditioning environments....

Mechanical joints, such as the bolted shear lap joint considered here, are ubiquitous in engineered structures, which realize vibration damping as well as load transfer from them. However, the prediction of the energydissipation characteristics of such joints remains a challenging problem. A cubic relationship between energy dissipated and load magnitude is often assumed in classical joint dyna...

Dissimilar metal joining between Al and Cu is effective for reducing the weight cost of electrical components. In this study, dissimilar lap pure to with an Al-Ni filler material was conducted using tungsten inert gas (TIG) arc brazing, effect Ni on joint strength associated microstructure intermetallic compound (IMC) layer at interface examined. The addition effectively increased interfacial j...

In order to achieve a high-quality joining of aluminum (Al) and copper (Cu) dissimilar metals, new friction stir double-riveting welding (FSDRW) with Cu rod as the rivet was proposed, rotating tool large concave angle shoulder specially designed. The results showed that under thermal–mechanical effect tool, deformed be double riveting heads structure anchor at upper surface Al plate an above la...

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...

Strength prediction is discussed using a traction-separation damage model incorporating material softening for bolted joint that fails in bearing mode. The modelliug approach in the bolted double-lap joint of current work is a simplistic approach to predict the strength of bearing failures. This is clearly shown in bearing failure which occurred experimentally at higher W/d ratios. A simple met...
