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 ...
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 new method for locating Roman transport infrastructure
(Elsevier Masson SAS, 2020-05)
Roman cities and roads, once correctly identified, can be appropriately conserved. Moreover, the correct identification of Roman transport routes will vindicate the accuracy of recent studies on the network of Roman transport ...
Analysis of DCB test of angle-ply laminates including bending-twisting coupling
(Elsevier, 2018-02-13)
Se analiza la fractura interlaminar de laminados simétricos y antisimétricos angulares mediante el método Double Cantilever Beam. Como los semi-laminados son simétricos en ambos casos, se produce un acoplamiento de ...
A study on the durability of structural concrete incorporating electric steelmaking slag
(Elsevier, 2018-02-10)
The durability of structural concrete mixes prepared with electric steelmaking aggregates is tested for use in normal and aggressive environments. Samples of “pumpable” and “self-compacting” concrete mixes are shown to ...
An engineering approach for the estimation of slewing bearing stiffness in Wind Turbine Generators
(Wiley, 2018-11-30)
The stiffness of yaw and pitch slewing bearings has a critical influence on the structural
behaviour of Wind Turbine Generators. Thus, it is commonly required by designers for
their simulations to estimate deformations ...
Friction torque in four-point contact slewing bearings: applicability and limitations of current analytical formulations
(Elsevier, 2017-11)
The friction torque is a key parameter in the design of slewing bearings. The most challenging issue in its calculation
resides in the modelling of rolling element contact mechanics. In this manuscript two models for the ...
Friction torque in four contact point slewing bearings: Effect of manufacturing errors and ring stiffness
(Elsevier, 2017-02-24)
This work outlines a procedure for the determination of the interferences between balls and raceways in four contact
point slewing bearings due to manufacturing errors. The procedure is applied to a particular case and ...
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) ...
