“…For most popular metals in FMLs such as aluminium and magnesium, the plastic behaviour is important and has a big impact on the response of the whole material. Different types of metal material models, including plasticity, are used: bilinear, isotropic hardening (multilinear) [8,27,30,67] with rate dependence [52], and with the Johnson-Cook constitutive model [6,10,17,18,51,64,68] also in simplified form [69]. Researchers use strain rate-dependent models (also including hardening) are used by researchers for different problems, including lowvelocity impact, which is a very popular test.…”

Fibre metal laminates (FML) are layered materials consisting of both metal and reinforced composite layers. Due to numerous possibilities of configuration, constituent materials, etc., designing and testing such materials can be time- and cost-consuming. In addition to that, some parameters cannot be obtained directly from the experiment campaign. These problems are often overcome by using numerical simulation. In this article, the authors reviewed different approaches to finite element analysis of fibre metal laminates based on published articles and their own experiences. Many aspects of numerical modelling of FMLs can be similar to approaches used for classic laminates. However, in the case of fibre metal laminates, the interface between the metal and the composite layer is very relevant both in experimental and numerical regard. Approaches to modelling this interface have been widely discussed. Numerical simulations of FMLs are often complementary to experimental campaigns, so an experimental background is presented. Then, the software used in numerical analysis is discussed. In the next two chapters, both static and fatigue failure modelling are discussed including several key aspects like dimensionality of the model, approaches to the material model of constituents and holistic view of the material, level of homogenization, type of used finite elements, use of symmetry, and more. The static failure criteria used for both fibres and matrix are discussed along with different damage models for metal layers. In the chapter dedicated to adhesive interface composite—metal, different modelling strategies are discussed including cohesive element, cohesive surfaces, contact with damage formulation and usage of eXtended Finite Element Method. Also, different ways to assess the failure of this layer are described with particular attention to the Cohesive Zone Model with defined Traction–Separation Law. Furthermore, issues related to mixed-mode loading are presented. In the next chapter other aspects of numerical modelling are described like mesh sensitivity, friction, boundary conditions, steering, user-defined materials, and validation. The authors in this article try to evaluate the quality of the different approaches described based on literature review and own research.

“…Fracture Mechanics methods are based on the direct application of the Paris law in combination with a procedure for the evaluation of the Energy Release Rate, as the Virtual Crack Closure Technique (VCCT) [6][7][8][9][10][11][12]. In Damage Mechanics approaches the degradation of the material interface is described by the evolution of one or more damage variables, and the Cohesive Zone Model (CZM) is adopted to represent the fracture [13][14][15][16][17].…”

Nanostrukturierte metallische Multilayer weisen eine wesentlich höhere Festigkeit, Ermüdungsfestigkeit und Duktilität als monolithische homogene Metallquerschnitte auf. Die überragenden strukturellen Eigenschaften nanostrukturierter Querschnitte sind bekannt, und so ist verwunderlich, warum bis heute kein Versuch unternommen wurde, nanostrukturierte Querschnitte in Makroquerschnitten im Konstruktiven Ingenieurbau zur Verbesserung der Querschnittseigenschaften einzusetzen. Dieser Aufsatz verknüpft die Vorteile der nanostrukturierten Multilayer mit den Bedürfnissen der homogenen metallischen Makroquerschnitte und geht der Frage nach, inwieweit das Hochleistungsmaterial Nanolaminat die konstruktiven Schwachstellen metallischer Infrastruktur ausgleichen kann. Die folgenden Schwachstellen der metallischen Konstruktion werden adressiert: 1) die Schweißnaht unter Ermüdungsbeanspruchung und Korrosion, 2) additiv gedruckte metallische Querschnitte unter Ermüdungsbeanspruchung und Korrosion. Der Aufsatz gibt Denkanstöße, wie nanostrukturierte Querschnitte möglicherweise die Zukunft im Stahlbau mitbestimmen können. Beispielhaft wird auf die Bemessung und Wartung von ermüdungsbeanspruchten metallischen Infrastrukturbauwerken, wie Brücken und Offshore‐Windenergieanlagen, eingegangen und aufgezeigt, wie Nachhaltigkeit, Ressourcenschonung, Senkung des CO2‐Fußabdrucks, Verfügbarkeit, Versorgungssicherheit und Wirtschaftlichkeit von Stahl‐Infrastrukturbauwerken potenziell erreichbar sind.
