Finite Element Analysis of Voided Reinforced Concrete Slabs Enhanced by GFRP Sheets under Monotonic and Repeated Loads

open access: yesJournal of Engineering
Six (1000*1000 mm2) slab specimens were cast and tested as two-way simply supported slabs previously (three under monotonic loading and three under repeated loading) are used in this research.

One-dimensional compression of a crushable sand in dry and wet conditions [PDF]

open access: yes, 2015
This paper presents the results of a series of dry and wet one-dimenional compression tests on a calcareous sand from the Persian Gulf. Calcareous grains crush more easily compared to silica grains, a fact that is mainly attributed to their angular shape

Flexural fatigue performance of CFRP prestressed concrete poles [PDF]

open access: yes, 2012
Carbon fibre reinforced polymer (CFRP) prestressed concrete poles offer a durable, light-weight alternative to conventional steel-reinforced or prestressed concrete poles.

Impact of repeated loading on mechanical response of a reinforced sand

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2019
Pavements constructed over loosely compacted subgrades may not possess adequate California bearing ratio (CBR) to meet the requirements of pavement design codes, which may lead to a thicker pavement design for addressing the required strength ...

Low force electrical switching using gold coated vertically aligned multi-walled carbon nanotubes surfaces

open access: yes, 2008
Gold coated vertically aligned multi-walled carbon-nanotubes (Au/MWCNT) surfaces are investigated to determine the electrical contact performance under low force conditions with repeated load cycling.

Experimental investigation of concrete fatigue resistance [PDF]

open access: yes, 2014
A lack of knowledge on the fatigue resistance of self-compacting concrete (SCC) structures has led to the research presented in this paper. Several reinforced concrete beams were subjected to both static and cyclic four-point bending tests in order to ...

Retardation effects due to overloads in aluminium-alloy aeronautical components [PDF]

open access: yes, 2017
Fatigue data are generally derived under constant-amplitude loading conditions, but aircraft components are subjected to variable-amplitude loading. Without interaction effects, caused by overloads and underloads intermingled in a loading sequence, it ...

Effect of vertical stress rest period on deformation behaviour of unbound granular materials: Experimental and numerical investigations

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2019
Repeated load triaxial test is used to assess the deformation behaviour of unbound granular materials (UGMs) in flexible road pavements. Repeated load pulse characteristics (i.e.
