Tissue Engineering plays a vital role in tissue construct to repair, maintain or replace tissues. Those tissues can be cultivated in vivo or in vitro using devices such as bioreactors. There are several approaches to ...
The main objective of the thesis is to study the bond behaviour of NSM FRP reinforcement in concrete elements. With this aim an extensive program of experimental tests complemented with numerical analysis has been performed ...
The use of composite materials in industrial applications such as aeronautical, aerospace or wind energy production has greatly increased in recent decades. Due to their inherent properties, these materials allow lighter, ...
In this work, we investigate harvesting thermoelectric energy from wasted heat in fluid networks and propose a generic tool for the simulation and sizing of thermoelectric energy harvesters, that can be used in ...
Adhesives have been shown to be an excellent solution for joining fibre reinforced polymer (FRP) components thanks to their capacity to redistribute loads, reduces stress concentrations and contribute to overall weight ...
The use of the stiffened panels in the aircraft/aeronautical industry has been growing in the last decades. On the other hand, the exponential growth in the use of composite materials in the last years has had a ...
La present tesi proposa una metodología per a la simulació probabilística de la fallada de la matriu en materials compòsits reforçats amb fibres de carboni, basant-se en l'anàlisi de la distribució aleatòria de les fibres. ...
Adhesive bonds could replace more traditional mechanical joints, making structures lighter and smoother. Stresses are distributed over a larger area, and dissimilar materials can be bonded, accommodating differences in ...
Currently, the use of Automated Fiber Placement technology allows, large composite aircraft components to be manufactured with high quality materials and introduce new laminate concepts. Among such concepts are the tow-steered ...
In this work, long-term behaviour of FRP RC beams has been investigated both analytically and experimentally to further extend the knowledge in this particular research domain. In this respect, a new methodology to determine ...
Virtual tools are commonly used nowadays to optimize product design and manufacturing process of fibre reinforced composite materials. The present work focuses on two areas of interest to forecast the part performance and ...
The main objective of work has been to study the bond strength and bond-slip response of NSM CFRP strips in concrete when subjected to sustained loading under different environmental conditions. To this end, two experimental ...
The rehabilitation of civil structures has been gaining importance during the last decades. Owing to their mechanical, corrosion resistance and lightweight properties, Carbon Fibre-Reinforced Polymers (CFRP) present an ...
In this work, a methodology has been developed to implement the bond behaviour between concrete and GFRP bars in the numerical modelling. Based on experimental results and applying the inverse method, the bond law to be ...
In recent years, additive manufacturing technologies (3D printing) have been introduced in different fields, such as locomotion and bioengineering, among others. Extrusion by Fused Deposition Modeling (FDM) or Fused ...
This research work proposes a novel automated and integrated system for the production and in vitro culture of scaffolds, called BioCell Printing. The main goal of the present research work, besides the development of the ...
The main objective of the thesis is to assess the damage resistance and damage tolerance of the non-conventional dispersed laminates and compare the response with the conventional ones. However, part of the effort is spent ...
When a fibre-reinforced composite laminate is subjected to traction or compression, it develops a relatively large Fracture Process Zone where material toughening mechanisms such as matrix cracking, ...
Cohesive zone models are widely used for modelling delamination and bonded joints under different loading conditions. In the current thesis, an objective inverse method has been developed to extract the cohesive law from ...
This thesis investigates the fatigue behaviour of fibre-reinforced composite laminates. Fatigue of composite materials is a complex subject both from an experimental and numerical modelling point of view. In this context, ...
