Abstract In this paper, the development of algorithm-based process models for mechanical joining self-pierce riveting with semi-tubular rivet (SPR-ST) is described. Therefore, an extensive experimental and numerical database regarding SPR-ST strength steel aluminum joints tensile strengths sheets between 200 1000 MPa was generated building models. This data could then be used training evaluatio...

In this study, the stress and deformation behavior of two I-corner plates with rivet connection in bending tension were investigated. Pure axial applied at end edge as boundary condition fixed support was defined other plates. The finite element method used. A suitable validation study conducted, its results compared literature cases. surface pressure to rounded I-corner. are shown form concent...

An integrated fatigue damage diagnosis and prognosis framework is proposed in this paper. The proposed methodology integrates a Lamb wave-based damage detection technique and a Bayesian updating method for remaining useful life (RUL) prediction. First, a piezoelectric sensor network is used to detect the fatigue crack size near the rivet holes in fuselage lap joints. Advanced signal processing ...

Studying the mixing of riverine freshwater and coastal water is the fundamental step to further understand the balance of a coastal/estuarine ecosystem (e.g., Hickey et al. 2010), seabed properties, sediment budgets (Gelfenbaum & Kaminsky 2010), and the sustainable management of the fluvial-estuary habitat (e.g., damming, dredging). The nearfield of a river plume represents an energetic environ...

Abstract In the publication, results of an experimental analysis joint formation by pressing DX51D steel sheets with thickness 1.5 (mm) use a rigid punch and additional deformable rivet various shapes were presented. The influence diameter d = 5 (mm), similar to dimensions forming in case classic clinching variety on interlock parameters was investigated. used die four movable segments—dedicate...

BACKGROUND & OBJECTIVE Originally isolated from severe human food-poisoning cases, Salmonella (3,10:r:-), a monophasic variety of otherwise diphasic serotypes such as S. weltevreden and S. simi, causes serious infections in man, animals and poultry. Mechanism of infection of this versatile and deadly organism is important to understand for its control. The objective of this study was to enhance...

The aim of this paper is to present a specification of speaker's communicative acts of utterances to be carried out gradually by using contextual and cotexual informations. Communicative act is defined as a communicative goal or aim which can be expressed in language L by a distinctive set of conventional cue patterns in specified discourse contexts. In our case, the communicative acts are clas...
