A review of the effects of cyclic contact loading on fretting fatigue behaviour
(Sage Publishing Ltd., 2020)A damage phenomenon called fretting fatigue frequently takes place when two contact bodies are clamped together under a normal contact load along with a small-scale oscillatory motion due to cyclic loading. In contrast to ... -
Broaching: Cutting tools and machine tools for manufacturing high quality features in components
(Elsevier Ltd., 2020)Broaching is a unique machining process with high accuracy and surface quality, which is employed in massand batch production for the manufacture of components with highly complex geometries. It involves the use of ... -
The contribution of microstructure and friction in broaching Ferrite–Pearlite steels
(Elsevier Ltd., 2020)Ferrite-Pearlite (FP) steels are used in many automotive components. However, their machinability in low cutting speed processes appears to be highly dependent on their metallurgical state. An experimental approach combining ... -
Mechanics of milling 48-2-2 gamma titanium aluminide
(Elsevier Ltd., 2020)Accurate and fast prediction of cutting forces is important in high-performance cutting in the aerospace industry. Gamma titanium aluminide (γ-TiAl) is a material of choice for aerospace and automotive applications due to ... -
Managing Multiple Projects in Uncertain Contexts: A Case Study on the Application of a New Approach Based on the Critical Chain Method
(MDPI AG, 2020)Uncertainty and change are two features of modern project management. They strongly influence the project management needs to operate in such contexts. This is the case when a complete and accurate definition of the scope ... -
Determination of emissivity and temperature of tool rake face when cutting AISI 4140
(Elsevier B.V., 2019)A method for measuring tool temperature in the tool/chip contact zone of the rake face of a tool during dry orthogonal cutting using thermography is presented. This method used a new calibration method that combined with ... -

(Elsevier Ltd., 2020)This study generated novel behavioural data for three engineering steels undergoing a turning process. The materialswere hardened 410, PH13-8Mo and 300M, two stainless steels and one high strength steel respectively. A ... -
On the Role of Contact and System Stiffness in the Measurement of Principal Variables in Fretting Wear Testing
(MDPI AG, 2020)In this work, the role of the contact stiffness in the measurement of principal variables in fretting wear tests is assessed. Several fretting wear tribometers found in the literature, including one developed by the authors, ... -
Incidental changes in orthographic processing in the native language as a function of learning a new language late in life
(Taylor & Francis Group, 2020)Acquiring a second alphabetic language also entails learning a new set of orthographic rules and specific patterns of grapheme combinations (namely, the orthotactics). The present longitudinal study aims to investigate ... -
Similar Conceptual Mapping of Novel Objects in Mixed- and Single-Language Contexts in Fluent Basque-Spanish Bilinguals
(John Wiley & Sons, 2020)Participants learned the meaning of novel objects by listening to two complementary definitions while watching videos of the new object, in a single‐language context (all in Spanish) or a mixed‐language context (one ... -
