Caracterização mecânica e biológica de scaffolds produzidos por BioCell Printing

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 ...

Characterization and optimization of dispersed composite laminates for damage resistant aeronautical structures

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 ...

A comprehensive methodology to analyse bonded joints subjected to different environmental conditions

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 ...

Designing, testing and modelling two innovative non-conventional buckling restrained braces for seismic resistant buildings

Piedrafita Francos, Daniel (Date of defense: 2014-12-01)

In this thesis two all-steel BRB have been designed, manufactured and tested, and both satisfy the testing protocols required by EU and US codes. They are composed of a steel slotted restraining unit which stabilizes the ...

Downward flame front spread in thin solid fuels: theory and experiments

Comas Hervada, Bruna (Date of defense: 2014-07-14)

Flame spread over solid samples has been studied from many points of view, as it is key for fire safety, yet it is a complex phenomenon that involves processes occurring in both the solid and the gas phases. This Ph.D. ...

Experimental and analytical study of delamination caused by free-edges and matrix cracks in laminated composites

Zubillaga Eceiza, Lierni (Date of defense: 2014-07-11)

In the last decades, the use of laminated composites, such as Carbon Fiber Reinforce Polymer has increased in many industrial sectors. Different failure mechanisms different damage mechanism can appear in laminated ...

Improving compression after impact response of composite laminates through ply level hybridization with thin plies and unsymmetrical designs

Sasikumar, Aravind (Date of defense: 2019-07-18)

Despite the weight savings, composite materials are vulnerable to impact loads mainly due to the alarming reduction in the compression after impact strength (CAI). This thesis exploits the potential of laminate designs ...
