Emara, Mohamed Reda Ali Elewa (Date of defense: 2018-04-17)
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 ...
Gómez Colom, Javier (Date of defense: 2022-01-14)
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 ...
Vilanova Marco, Irene (Date of defense: 2015-10-20)
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 ...
Arbeláez Toro, Juan José (Date of defense: 2023-04-26)
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 ...
Domingos, Marco (Date of defense: 2013-10-04)
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 ...
Sebaey Abdella, Tamer Ali Abdella (Date of defense: 2013-01-11)
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 ...
Ortega Novillo, Adrián (Date of defense: 2017-04-20)
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, ...
Abdel Monsef, Said Ahmed Ibrahim (Date of defense: 2020-07-02)
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 ...
Llobet Vallejo, Jordi (Date of defense: 2020-01-17)
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, ...
