Advanced Manufacturing Centres, Practical Model to Boost Technology Transfer in Manufacturing
(MDPI, 2019-09)
Establishing collaboration strategies with interdisciplinary networks in research is a crucial success factor for the companies in any sector, especially in manufacturing for aeronautics. In the aeronautical supply chain, ...
Prediction Methods and Experimental Techniques for Chatter Avoidance in Turning Systems: A Review
(MDPI, 2019-11)
The general trend towards lightweight components and stronger but difficult to machine materials leads to a higher probability of vibrations in machining systems. Amongst them, chatter vibrations are an old enemy for ...
Sensitivity Analysis of Tool Wear in Drilling of Titanium Aluminides
(MDPI, 2019-03-06)
In the aerospace industry, a large number of holes need to be drilled to mechanically connect the components of aircraft engines. The working conditions for such components demand a good response of their mechanical ...
Oscillating U-Shaped Body for Underwater Piezoelectric Energy Harvester Power Optimization
(MDPI, 2019-10-30)
Vibration energy harvesting (VeH) techniques by means of intentionally designed mechanisms have been used in the last decade for frequency bandwidth improvement under excitation for adequately high-vibration amplitudes. ...
Modeling the environmental sustainability of timber structures: a case study
(Elsevier, 2019-07-16)
A revival in timber buildings and the appreciation of their positive physical and mechanical properties can be explained by the unique environmental credentials of timber products and their versatility. Heightened public ...
Sustainability Improvement in the Design of Lightweight Roofs: A New Prototype of Hybrid Steel and Wood Purlins
(MDPI, 2019-01-01)
A new structural typology of a hybrid purlin, made of type C cold steel and rectangular laminated wood (SWP), is presented in this paper. As a result, improvements on the most commonly used steel purlins are achieved, by ...
Load distribution and friction torque in four-point contact slewing bearings considering manufacturing errors and ring flexibility
(Elsevier, 2019-03-16)
This work introduces a methodology for the calculation of the load distribution in four-point contact slewing bearings
considering ball preload, manufacturing errors and ring flexibility. The model is built by the formulation ...
A novel experimental procedure to determine the cohesive law in ENF tests
(Elsevier, 2019-01)
This study presents a novel method to determine the mode II cohesive law of unidirectional carbon fiber reinforced polymer laminates, employing the End Notched Flexure (ENF) test.
The fracture toughness in mode II (G) ...
Rigid pavement performance models by means of Markov Chains with half-year step time
(Taylor & Francis, 2019-07-03)
[EN] Pavement management systems employ pavement performance models to plan the most effective allocation of public funds. The most used models are the deterministic and the probabilistic or stochastic ones. Among stochastic ...
Overhang constraint for topology optimization of self-supported compliant mechanisms considering additive manufacturing
(Elsevier, 2019-04)
This work presents a computational procedure for direct integration of Topology Optimization and Additive Manufacturing (AM) technologies for compliant mechanisms design. Many topologically optimized geometries present ...
