A novel computational homogenization theory for multilayered plates: the multiscale 2D+ approach
(English) This doctoral thesis presents a novel multiscale theory for the analysis of multilayered plate structures, termed the "Multiscale 2D+ approach" or, simply, "2D+". Based on the formalism of computational ...
Interoperable dynamics-based structural health monitoring framework for civil engineering structures
(English) The methods used nowadays for maintenance and control of infrastructures require modernisation due to the fact that these are based in processes such as visual inspections, which are carried out sporadically in ...
Development of a unified fatigue constitutive model: from high to low cycle regime
(English) n a context in which research lines such as optimised design, smart design, use of new materials, weight reduction, etc. are becoming more and more common in the engineering field, techniques that allow for an ...
Numerical approximation of thin structures using stabilized mixed formulations for infinitesimal and finite strain theories, including fluid-structure interaction problem applications
(English) The theories of thin structures can be classified into two main branches depending upon whether shear deformation in the transverse direction is taken into consideration or not. In this context, theories accounting ...

Study of hybrid FRP-FRCM superficial structural elements
(English) The most common composite materials for strengthening building structures are divided into two dif ferent types based on the matrix’s composition, organics (polymers) or inorganics (cement, lime). The hybrid ...
Computational and experimental thermo-mechanics of metal additive manufacturing : stress, warpage, cracks and properties
The objectives of this thesis are (i) to understand the thermal, metallurgical and mechanical behavior during AM, (ii) to shed light on the generation of residual stresses and the stress-induced deformations and cracks, ...
Improvement of down-aisle stability and ductility for unbraced adjustable pallet racking systems
Pallet racking systems are structures intended to store products. Their proper structural design is of paramount importance as its collapse can lead to significant economic losses and even human. This type of structures ...
Study of the structural behavior of hybrid elements of carbon fiber reinforced polymer and concrete
Creating sustainability and public infrastructure is a fairly recent subject the engineering community has been debating. Introducing new building materials or introducing new structural designs is a strategy for constructing ...
Numerical modelling of viscoelastic flows based on a log-conformation formulation
Viscoelastic fluids are a type of non-Newtonian fluids which are formed by complex internal structures and high-molecular-weight, whose typical examples are the polymer solutions and molten polymers. Also, the viscoleastic ...
Numerical modeling of the underwater acoustic impact of offshore stations
The design of offshore power stations (for wind, wave or tidal energy generation) requires assessing their environmental impact. In particular, it is of the major importance to predict the impact of the generated subsea ...
A fully Lagrangian formulation for fluid-structure interaction between free-surface flows and multi-fracturing solids
It is well known that in civil engineering structures are designed so that they remain,whenever possible, in an elastic regime and with their mechanical properties intact. The truth isthat in reality there are uncertainties ...
BEST : Bézier-Enhanced Shell Triangle : a new rotation-free thin shell finite element
A new thin shell finite element is presented. This new element doesn’ t have rotational degrees of freedom. Instead, in order to overcome the C1 continuity requirement across elements, the author resorts to enhance the ...
