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. ...
The Gender Perspective of Professional Competencies in Industrial Engineering Studies
(MDPI, 2020-04-07)
Sexism and gender relations in higher education require special attention and are a topic of great interest in regulations related to education. The low participation percentage of women in Science, Technology, Engineering, ...
Computational Modelling of Rectangular Sub-Boundary Layer Vortex Generators
(MDPI, 2018-01-19)
Vortex generators (VGs) are increasingly used in the wind turbine manufacture industry as flow control devices to improve rotor blade aerodynamic performance. Nevertheless, VGs may produce excess residual drag in some ...
Calibration patterns for predicting residual strengths of steel fibre reinforced concrete (SFRC)
(Elsevier, 2013-11-12)
Steel Fibre Reinforced Concrete (SFRC), a composite construction material, needs reliable prediction and control techniques to promote its use in structural applications. The distribution and orientation of fibres within ...
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 ...
The Weldability of Duplex Stainless-Steel in Structural Components to Withstand Corrosive Marine Environments
(MDPI, 2020-11-05)
There is still a considerable gap in the definition of the weldability of Duplex Stainless Steel (DSS). A lack of clarity that is explained by the standard specification of the maximum content of equivalent carbon that ...
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 ...
Effect of the Martensitic Transformation on the Stamping Force and Cycle Time of Hot Stamping Parts
(MDPI, 2018-06)
Stamping dies perform two functions in the hot stamping process of body-in-white components. Firstly, they form the steel sheet into the desired shape and, secondly, they quench the steel at a cooling rate that leads to ...
A novel procedure to determine the cohesive law In DCB tests
(Elsevier, 2017-11-10)
A novel method is presented for the determination of mode I cohesive law for the characterization of delamination in unidirectional carbon fiber reinforced polymer laminates. The energy release rate as a function of the ...
A New Approach For Determining The R-Curve In DCB Tests Without Optical Measurements
(Elsevier, 2015-02)
A new method for obtaining the R-curve point to point by the Double Cantilever Beam test is proposed. Besides the determination of new compliance and energy release rate equations, the analytical model presented leads to ...
