Comparison between the stiffness method and the hybrid method applied to a circular ring
(Springer, 2018-01-17)
This study deals with the comparison of stresses and displacements of a circular ring obtained by two numerical formulations, namely the stiffness method and the hybrid method, applied to isoparametric quadrilateral elements. ...
Dimensional stability of Electric Arc Furnace slag in civil engineering applications
(Elsevier, 2018-09-15)
Dimensional stability of manufactured aggregates represents a matter of interest for many applications in civil engineering. Past results evidenced how steel slag might be affected by potential swelling, due to several ...
Analysis of the modal choice of transport at the case of university: Case of University of the Basque Country of San Sebastian
(Elsevier, 2017-04-11)
Transportation has significant and long lasting economical, social and environmental impacts, and so is an important dimension of urban sustainability.
Any effort that is made to achieve sustainability must take into ...
Direct integration of the equations of multibody dynamics using central differences and linearization
(Elsevier, 2018-12-12)
A methodology for integrating rigid body dynamics for the analysis of multibody systems is presented. The novelty lies in the fact that the equation system is solved directly by means of central differences as a second-order ...
Control loop tuning by thermal simulation applied to the laser transformation hardening with scanning optics process
(Elsevier, 2016-04)
Laser transformation hardening with scanning optics (LTHS) is a novel manufacturing process on a very preliminary stage of introducing it in the surface treatment industry. The key to ensure the success in this process is ...
Analysis and Characterization of the Behaviour of a Variable Geometry Structure
(SAGE, 2007-11)
The study about a variable geometry truss is presented. The first step is a kinematic design and later an analysis using the MSC/Adams code. Then, the finite-element method with the MSC/Nastran code was used to develop a ...
Evaluation of efficiency and mechanical properties of Inconel 718 components built by wire and powder laser material deposition
(Emerald Publishing Limited, 2017-10-17)
PurposeThe purpose of this paper is to evaluate and compare powder and wire laser material deposition (LMD) processes.Design/methodology/approachIn the present paper, Inconel 718 tensile test probes were built layer by ...
Internal characterization and hole formation mechanism in the laser percussion drilling process
(Elsevier, 2013-09-09)
Laser percussion drilling is increasing its relevance in many industrial applications, being used particularly in the aircraft industry in performing the micro-holes in nickel based alloys turbine blades for cooling, or ...
Evaluation of the relevance of melt pool dynamics in Laser Material Deposition process modeling
(Elsevier, 2017-07-14)
The melt pool dynamics consideration in the numeric modeling of the Laser Material Deposition (LMD) process can be enormously difficult and expensive, especially if this calculation is not strictly necessary. The increased ...
Experimental assessment of an End Notched Flexure test configuration with an inserted roller for analyzing mixed-mode I/II fracture toughness
(Elsevier, 2016-09)
This study describes the experimental work related to a test configuration proposed recently, based on an End Notched Flexure test configuration modified with an inserted roller. Various mixed-mode ratio tests have been ...
