“…As a second step, to describe the plastic behavior of the connector element, equivalent yield force (f) and equivalent plastic relative motion (u¯p l ) are required. An independent force-displacement hardening law is proposed in shear and normal directions of the connector [29]. These hardening laws are calibrated using the experimental results of the reference tension and shear tests [10].…”

Considering the significant strain‐hardening and ductility characteristics of stainless steel and the influential role of beam to column joints in the overall response of structures, a clear understanding of their moment rotation behaviour appears fundamental. In the present study, a review of the European design code for three typical semi‐continuous beam‐to‐column joints (extended end plate, flush end plate and top‐and‐seat angle connections) is first carried out. Then, using a hybrid modelling strategy with uncoupled elastic‐plastic springs for the bolts and shell elements for the members, more refined 3D finite element (FE) models are developed and validated against available test results. An equivalent stress definition is then proposed for calculating the joint moment resistance. Finally, the initial rotational stiffness, moment resistance, rotation capacity, and failure patterns are used to evaluate critically the accuracy of the predictions of the European design code. As a result, the need for more comprehensive design guidance in accordance with the observed findings is pointed out.

“…The purpose of Breda et al's work [138] is to evaluate the effect of plastic anisotropy of the base material on the elastic and plastic calibration of an equivalent joint model for clinched connections. It can be concluded that the incorporation of an anisotropic yield function does not affect the elastic-plastic shear calibration parameters.…”

Clinching technology is a mechanical connection technology that is applied to connect metal or non-metal sheet materials. It is widely used in different applications, such as automobile, aircraft, household appliances and other industries. In order to reduce weight, save energy, reduce fuel consumption, reduce pollution and curb global warming, lightweight structures with clinched joint are increasingly used in transportation. The finite element technology is popularized in engineering, so that it can get similar results with the test after investing less time, manpower, energy and material resources, which is conducive to the prediction and smooth progress of the test. A review of the finite element analysis of clinching technology is provided in the present paper. The article's work also discusses the strength of the clinched joint, the factors influencing the clinched joint's strength, the failure mechanism of the clinched joint, etc. Furthermore, the novel technologies of clinching as well as the finite element models and methods used in clinching, are introduced. The present paper's main objective was to review the recent developments in the finite element analysis of clinching and provide a basis for further investigation in this area of research.

Ebben a cikkben a klincselt kötések egyszerűsített végeselemes modellezési eljárásának egy lehetséges megoldása kerül bemutatásra. A modellezést anyagvizsgálatok előzték meg, amelyek alapján a modell kalibrációja megtörtént. A modell érzékenységéről röviden szó lesz. Jelen cikk az egyszerű, húzó terhelésnek kitett kötések vizsgálatával foglalkozik, de fontos megjegyezni, hogy további modellek felépítésével a jellemző terhelési irányok, igénybevételek esetére is felépíthető az eljárás. Az egyszerűsített modellezési eljárás az ipari gyakorlatban alkalmazható, több kötés szilárdságának egyszerre történő vizsgálata során, amely vizsgálatokkor nem a technológiát, azaz a klincselést vizsgáljuk, hanem a szerkezetben való viselkedését.
