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 ...
On The Influence of Rotary Dresser Geometry on Wear Evolution and Grinding Process
(MDPI, 2019-11-22)
Dressing is a critical issue for optimizing the grinding process. Dresser tool and dresser
parameters must be designed according to the grinding wheel material, shape, or even the dimensional and geometrical tolerances ...
Assessment of the influence of façade location and orientation in indoor environment of double-skin building envelopes with perforated metal sheets
(Elsevier, 2019-08-03)
Double-skin perforated sheet façades, enclosures consisting of perforated screens, air chambers and glass/wall sheets, are features of modern building design that are winning greater acceptance. A detailed analysis of their ...
Skid resistance prediction for new two-lane roads
(ICE Publishing, 2019-10)
[EN]Skid resistance is a vital issue in pavement management, mainly in relation to road safety; hence, road agencies must assure a minimum friction level of their road networks. The regional government of Biscay (Spain) ...
Modelling the wear evolution of a single alumina abrasive grain: analyzing the influence of crystalline structure
(Elsevier, 2019-10-17)
The grinding process is continuously adapting to industrial requirements. New advanced materials have beendeveloped, which have been ground. In this regard, new abrasive grains have emerged to respond to the demands of ...
Failure-Analysis Based Redesign of Furnace Conveyor System Components: A Case Study
(MDPI, 2019-08)
Any manufacturing equipment designed from scratch requires a detailed follow-up of the performance for the first units placed in service during the production ramp-up, so that lessons learned are immediately implemented ...
