The use of adhesive joints in industrial structural applications is currently growing. Nevertheless, the designing process is still a challenge for engineers because there is a lack of effective models to predict their ...
The primary objective of this research is to modify the models regularly used to record and monitor the implementation costs of public works projects from the perspective of the promotor, the project directors or the project ...
El uso de los composites en la industria aeronáutica ha experimentado un fuerte crecimiento en los últimos años debido a la utilización de componentes de composite que realizan funciones estructurales. A menudo, para ...
This document presents a methodology that (using tunable finite element models) allow validating during the development phase of the project, the behavior that equipment and mechanical systems will have once they are ...
La feina feta en aquest treball de tesis s'ha desenvolupat a partir de tres objectius vertebradors, que fonamentalment són:<br/>·El primer dels objectius d'aquest treball de tesis és presentar un recull dels factors que ...
Triple negative breast cancer (TNBC) accounts for 15-20% of the breast cancers and displays an aggressive profile, poor prognosis, high relapse risk and does not have a targeted therapy. In the last years, breast cancer ...
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 ...
Since the beginnings of the automotive driven with internal combustion engines all the cycles used in the alternative motors share a thermal characteristic, a large amount of heat released by the fuel is lost in the form ...
Advanced joining technologies such as bonded joints play an important role to develop more efficient and durable structures. The present Thesis gives a step forward and proposes different solutions to characterise the ...
Fiber reinforced composite materials are nowadays used in several industrial applications that pursue structural weight reduction to reduce fuel consumption. The stiffness-to-weight and strength-to-weight ratios of composite ...
The overall purpose of this Ph.D. thesis is to contribute to the reliable design of composite structures subjected to fatigue-driven delamination. The aim is motivated by a wish to reduce the amount of experimental testing ...
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. ...
In recent years, the use of composite materials in the aeronautic, automotive, marine construction, etc. has increased significantly. Hence, there is an increasing need for repair technologies on primary structural components, ...
There is a general trend towards rehabilitation and strengthening of existing reinforced concrete (RC) structures due to the costs associated with the replacement of the structural members and the environmental impact ...
This doctoral thesis explores HR management through systems of production incentives in the construction sector which has been instrumental to the Spanish economy. The transformation of a time-based payment system to a ...
The current work is focused on two areas related to thermoelectricity: (i) the study of the capability of controlling the thermal conductivity of TEMs and (ii) the development, testing and improvement of an automotive ...
First part of this research is focused in validating the Exhaust Gas Heater (EGH) viability in reducing NOx emissions without negative effects in a standard exhaust gas circuit. Experimentation was held using a HDV Euro ...
NSM strengthening technique under the influence of temperature and relative humidity, in which the interaction between materials involved is analyzed, is studied in this PhD. Therefore, this work is aimed at contributing ...
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 ...
The present thesis aims at developing robust numerical and experimental methods for the simulation of composite adhesive joints. Firstly, a new method for the experimental characterization of adhesive joints is presented. ...
