Unemployment benefits : discursive convergence, distant realities

Production of INCASI Project H2020-MSCA-RISE-2015 GA 691004Unemployment protection systems have certain characteristics in common in Argentina, Uruguay, Spain and Italy: they are compulsory and contributory-proportional, although in Uruguay, it also has a capitalisation supplement. Despite the similarities, they work differently because the context of informal employment chiefly, and unemployment, low salaries and precariousness differ greatly. Consequently, the unemployment protection coverage rate varies. Theories of the Active Welfare State, the Investor State and the reforms of unemployment protection systems have led to a certain modernising language being adopted in these countries: activation, employability, conditionality, lifelong learning, flexibility, which are, among others, words shared with Europe. However, the meanings of these words differ according to the institutional context of each country. In Latin America the welfare state is low institutionalised even almost non-existent, while in Europe it is a diverse institution. Despite this, the four countries share an upward trend in benefit policies, in accordance with the increase in poverty risk

Mechanical design and modelling of lightweight additively manufactured lattice structures evolved from regular three-dimensional tessellations

To lower costs and improve efficiency, most additively manufactured parts are printed as thin shells filled with a lightweight cellular material, which reacts to secondary stresses and provides distributed support to the load-carrying outer casing. This paper proposes a two-step method to design filling metamaterials that are intrinsically strong, stiff and lightweight. First, the space is divided into repetitive volumes according to available three-dimensional tessellation schemes. The tessellation is then transformed into a trabecular wireframe by converting each unit volume into a kinematically-rigid open cell with edge beams and bracings. Dimensional analysis allows the lattice structures to be characterized mechanically and elastically with a finite number of simple computational analyses. The paper shows that the properties of metamaterials with triangular, square and hexagonal prismatic cells compare favourably with state-of-the art porous materials like foams and honeycombs

From three-dimensional tessellations to lightweight filling materials for additively manufactured structures: Concept, simulation, and testing

To improve the structural efficiency and reduce costs, most additively manufactured parts are printed as thin shells filled with a lightweight cellular material. The filling material reacts to secondary stresses and provides distributed support for the load-carrying outer shell. In a recent publication, the authors have proposed a two-step method to design lightweight filling metamaterials that are intrinsically strong and stiff. Conceptually, the space is first divided into repetitive volumes according to known three-dimensional tessellation schemes. The tessellation is then replaced by a kinematically rigid wireframe with beams along the edges and across the faces of the native volumes. Elaborating on that idea, the present paper pursues three objectives: (a) show the variety of material designs that derive from the tessellation-wireframe approach; (b) characterize the materials through finite element analyses on full-scale models and compare them with former predictions based on scaling and homogenization techniques; (c) validate the numerical results against experimental tests on a selection of prototype structures. Good correlation is revealed between theoretical predictions, computational models, and experimental data
