The fast growing field of metamaterials opens a number of new opportunities and applications but, at the same time, introduces many challenges in the design and modeling. The two scale asymptotic homogenization appears as a promising tool for the design and optimization of systems composed of metamaterials. In this contribution we will discuss the role of homogenization in the development of practical applications of metamaterials. Focus will be in particular on two significant examples: the optimization of auxetic metamaterials for energy absorption and the design of a system for energy localization that includes locally resonant materials. In both cases the metamaterial is substituted with an equivalent homogenized continuum allowing for a fast parametric optimization and leading to a significant computational advantage.

Bioinspiration is a paradigm that extracts design principles from biological and natural systems. Based on that, it is possible to create systems and structures with adaptive behavior according to its environment. Smart materials have an essential importance on this idea being used as sensors and actuators that define the remarkable system characteristics. Besides this, natural rhythms are inspiring new situations and therefore, the investigation of nonlinear dynamics, chaos and control is establishing other design paradigms. The use of bioinspired smart systems is now evolving to create origami systems based on the ancient Japanese art of paper folding. The main idea of the origami is to create a three dimensional structure from a plane source. Adaptive origami systems have been explored to produce foldable, adaptive structures that can be applied in several areas of the human knowledge. This presentation deals with a general overview of nonlinear mechanics of smart bioinspired systems and structures. Shape memory alloy systems, origami systems, mechanical energy harvesting, chaos and chaos control are some subjects presented to give a general idea of the subject. The rich, complex dynamical response of these systems is of special concern.

As severe environmental policies are being implemented, engineers and designers are compelled to reduce structural weight of conventional vehicles and airplanes to mitigate greenhouse gas emissions. Future electric-powered and hydrogen-powered aircraft concepts will require heavy battery blocks, fuel tanks or cells. Therefore high-performance lightweight structures will play an important role in improving autonomy of future aerial and terrestrial vehicles. Metal/fiber-reinforced polymer hybrid structures (MP-HS) are potential candidates to fulfill this demand. These hybrid structures are characterized by the presence of solid interface(s), normally with a sharp gradient in properties. The intrinsic dissimilarity between metals and polymer/composites imposes huge engineering challenges, requiring creative and material-friendly manufacturing approaches. Currently, the state-of-the-art production of MP-HS – e.g. the hybridization of the metal with composites via semi-automated lamination techniques – is very time consuming. Moreover, several complex geometries, such as those having internal 3D-features, cannot be usually manufactured. The combination of metal and fiber-reinforced polymer additive manufacturing (AM) with energy efficient joining technologies, has the potential to overcome these shortcomings. This keynote lecture will assess current results on the AM and joining of metal-fiber reinforced thermoplastic hybrid structures. Focus will be given on case-studies combining laser powder bed fusion (L-PBF), fused-filament fabrication (FFF) and friction-based joining processes.

In this lecture we will talk about our hyperelastic model, its genesis, and its performance in solving cases of academic as well as industrial importance. The model has been extended to deal with hysteretic effects and anisotropic elastomers, too. We will also talk about the bad and good practices and recommendations when calibrating and choosing among so many hyperelastic constitutive models available.

From 1982 until today the finite element method has evolved considerably. In this talk I want to convey my experience in studying the method and develop a software that accompanies the main research lines. In 1986 finite elements were extended with hp-adaptivity. Hp-adaptive meshes are the only method capable of yielding convergent results for singular problems. The complexity of coding 3d hp motivated the creation of the object-oriented finite element library NeoPZ. The object oriented paradigm allows to hide the complexity of the underlying data structure behind a simple user interface. Applying continuous interpolation spaces to approximate convection dominated problems required special operators such as SUPG. This motivated the development of numerical formulations where the approximation spaces are not continuous, known as broken spaces. The combination of applying SUPG with broken spaces and Riemann solvers allows to obtain high order approximations for convection dominated problems. Motivated by research in collaboration with the petroleum industry local conservative methods where local conservation is satisfied. As a result, NeoPZ was extended with H(div) approximation spaces, which in combination with an appropriate Lagrange multiplier space leads to pointwise conservative approximations. Motivated by the need of simulating signal transmission and as a natural extension of the library H(curl) approximations were added making the NeoPZ library complete. Many other technologies have been incorporated in the library through the contribution of master’s and Phd students. In the talk we will show curved geometries, h-refinement patterns, multi-physics approximations, multi-scale approximations and error estimation techniques.

Fracture mechanics can be understood as the area of science that studies the propagation of fractures, cracks, slits, and other flaws from mechanical processes that may negatively affect the strength of the material. Traditionally, the concepts on which the strength of the materials are based do not consider the toughness to fracture of the material, which can be defined as the property that quantifies the resistance to crack propagation. The essence of these studies can be applied to any type of material, such as in the medical field when studying the behavior of bone fractures. This type of fracture usually arises through high-energy trauma. Bone, under normal conditions, can support loads and absorb this energy. However, if there is a high level of energy associated with the trauma, the bone cannot support it and ends up suffering a fracture. This paper aims to develop a numerical microscale analysis of a bone fracture using the Extended Finite Element Method (XFEM). This dissertation studies two-dimensional simulations of the initiation and propagation mechanisms of an initial fracture in a compact bone unit called the osteon, which is bounded by the cement line, a zone that is low in type 1 collagen. In this way, it will be possible to understand the influence of the cement line on the propagation of the microscale fracture.
