This work presents a computational tool, based on the finite element method, for the analysis of two-dimensional structural components subjected to fatigue. This tool, called QUEBRA2D, estimates, through well-known empiric models for fatigue life prediction, the number of cycles necessary for a crack to reach a specific size when subjected to constant(More)
Many research theories try to explain the adoption/rejection of technology by the users. One of them focuses on the study of the acceptance and the intention of its use and it is named Unified Theory of Acceptance and Use of Technology (UTAUT). The main goal of this article is to model the verification of the adequacy of UTAUT to the use of information(More)
In the last decades we have witnessed a technological advancement at all levels with particular emphasis in hardware and mobile devices. These became increasingly lighter and cheaper, and transferred from the office to the car, to equipment and other utensils. The amount of (digital) information available in the environment has increased exponentially,(More)
In this article, a preliminary analysis of the use of Information and Communication Technologies (ICT) in the context of Higher Education (HE) takes place. This analysis seeks to verify if it there has been, in particular, a change of practice by teachers and whether this occurrence could be related to the introduction of the Bologna model, making the(More)
