“…To consider unidirectional fiber-reinforced plastics composites sheets, certain modifications are to be made to the presented constitutive model, see [32,40,41]. In contrast to short fiber-reinforced plastics composites, in unidirectional fiber-reinforced plastics composites it has been shown that there exists, to a large extent, plastic in-extensibility along the fiber direction [33].…”

A 3D FEM-based virtual test-rig tool for the hybrid metal-composites clinching technology is developed and built in the commercial finite element software Abaqus. The proposed tool consists of two modules: a module to simulate the hybrid clinching process and another to predict the strength of the clinched joints. At first, experimental results concerning the hybrid metal-composites (EN AW-5754-PA6GF30) clinching are presented. Then, the developed virtual tool is described in detail outlining the constitutive models implemented for the hybrid pairing sheets as well as illustrating the proposed FE numerical procedures. Later, the developed tool is applied to the hybrid pairing EN AW-5754-PA6GF30. In comparison to the conducted experiments, the simulation results obtained show the applicability and accuracy of the developed virtual testing tool. Keywords: Metal / composites / multi-material design / hybrid clinching / virtual testing / finite element method (FEM) Ein dreidimensionales FEM-basiertes Simulationsmodell zur virtuellen Prüfung von hybriden Clinchverbindungen aus Faser-Kunststoff/Metall-Verbunden wurde entwickelt und in der kommerziellen Finite-Elemente-Software Abaqus aufgebaut. Das Simulationsmodell besteht aus zwei Berechnungsmodulen: Einem zur Simulation des hybriden Clinchprozesses, und einem weiteren zur numerischen Vorhersage der Festigkeit der hybriden Clinchverbindung. Zunächst werden experimentelle Ergebnisse zum hybriden Clinchen der Faser-Kunststoff/Metall-Verbunde (EN AW-5754 / PA6GF30) vorgestellt. Anschließend wird das entwickelte Berechnungsmodell detailliert beschrieben, wobei hier insbesondere auf die konstitutiven Materialmodelle, die für die einzelnen Fügeparameter in Abaqus implementiert worden sind, sowie auf das Simulationsverfahren eingegangen wird. Nach Berechnung des hybriden Clinchprozesses und erfolgreicher Modellvalidierung wird das Berechnungsmodul zur virtuellen Prüfung der Verbindungsfestigkeit angewandt. Durch den Vergleich der Simulationsergebnisse mit den experimentellen Daten wird die Anwendbarkeit und Genauigkeit des hier entwickelten virtuellen Prüfstands aufgezeigt.

“…In this study, textile waste fibers were confined in textile mesh glass fiber and used as central layer of lightweight concrete. Textile mesh glass fibers are ecofriendly materials that are made of alkali resistance fibers and can be used for 2 Advances in Civil Engineering reinforcing thin and lightweight parts of concrete [14][15][16][17][18][19]. These properties were major cause of using textile meshes in lightweight concrete.…”

This investigation is focused on bending experiment of some prismatic perlite lightweight concrete. In these samples, textile waste fibers are confined with textile mesh glass fiber and embedded in the central part of cubic lightweight concrete specimens. Bending experiments revealed that lightweight concrete panels with a core of textile waste fiber have less density than water and high energy absorption and ductility. Furthermore, these composite panels by having appropriate thermal insulation characteristics could be used for partitioning in the buildings.

“…The authors concluded that such multiscale virtual tests should be able to complement and replace experimental tests; this is chiefly because of their robust predictions and wider design, characterization and testing possibilities. Rolfes [64] subsequently improved the prediction of multiscale progressive failure of textile composites by Ernst and co-workers [63]. The authors developed an orthotropic layer-based failure criterion for modelling the progressive failure of non-crimp fabrics.…”

AbstractThis paper documents the emergence of virtual testing frameworks for prediction of the constitutive responses of engineering materials. A detailed study is presented, of the philosophy underpinning virtual testing schemes: highlighting the structure, challenges and opportunities posed by a virtual testing strategy compared with traditional laboratory experiments. The virtual testing process has been discussed from atomistic to macrostructural lengthscales of analyses. Several implementations of virtual testing frameworks for diverse categories of materials are also presented, with particular emphasis on composites, cellular materials and biomaterials (collectively described as heterogeneous systems, in this context). The robustness of virtual frameworks for prediction of the constitutive behaviour of these materials is discussed. The paper also considers the current thinking on developing virtual laboratories in relation to availability of computational resources as well as the development of multi-scale material model algorithms. In conclusion, the paper highlights the challenges facing developments of future virtual testing frameworks. This review represents a comprehensive documentation of the state of knowledge on virtual testing from microscale to macroscale length scales for heterogeneous materials across constitutive responses from elastic to damage regimes.
