Efficient assembly of bolted joints under external loads using numerical FEM
(Elsevier, 2018-05-16)
Several factors can cause leakages in a bolted flange connection, external loads being the
most important one. External loads such as those produced by misalignment introduce an
external axial load combined with a bending ...
Effect of microwave heating damage on the electrical, thermal and mechanical properties of fibre-reinforced cement mortars
(Elsevier, 2018)
Nowadays, refurbishing of existing structures has gained interest in order to reduce both the construction materials used and the construction and demolition waste production. For that purpose, there are several methods ...
Bonding strength of stainless steel rebars in concretes exposed to marine environments
(Elsevier, 2018-05-30)
[EN] Many studies have corroborated the use of Stainless Steel Reinforcements (SSR) for structures in corrosive environments. However, even though the conditions for their employment are specified in different standards, ...
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 ...
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 ...
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 ...
