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 ...
Hardness, grainsize and porosity formation prediction on the Laser Metal Deposition of AISI 304 stainless steel
(Elsevier, 2018-08-14)
[EN] The presented numerical model solves the heat and mass transfer equations in the Laser Metal Deposition process and based on the evolution of the thermal field predicts the grainsize, the resulting hardness and evaluates ...
Thermal performance of sawdust and lime-mud concrete masonry units
(Elsevier, 2018-04)
Over the past three decades, growing interest in the properties of thermal envelopes and their enhancement has led to the development of new sustainable materials. Nevertheless, Concrete Masonry Units (CMUs) with negligible ...
On the development and evolution of wear flats in microcrystalline sintered alumina grinding wheels.
(Elsevier, 2018-03-26)
Wheel wear is a critical issue for grinding process optimization. This is why it receives so much attentionboth from Academia and industry. The development of new generations of abrasive wheels requiresimproving the ...
Super abrasive machining of integral rotary components using grinding flank tools
(MDPI, 2018-01-01)
Manufacturing techniques that are applied to turbomachinery components represent a challenge in the aeronautic sector. These components require high resistant super-alloys in order to satisfy the extreme working conditions ...
Sustainable Alternative of Structural Concrete Retaining Tanks
(Emerald Publishing, 2018-05)
The environmental footprint of the construction industry requires the quantification of new developments to appraise their sustainable contribution. Recent developments in relation to the merging of steel fibre reinforced ...
