Under high confinement, defined as confinement sufficient to suppress frictional sliding, brittle-like failure is still observed, even at pressure well below that required for faulting associated with phase transformations.
It finally presents the confined cylinder tests as a standard type of tests to determine the efficiency factor of a particular FRP product in confinement applications, defined as the ratio between the actual hoop rupture strain of FRP in FRP-confined concrete and the ultimate tensile strain from material tests generally conducted using flat coupons.
Tracks were then quantified for number, speed, length, duration, displacement and confinement ratio (defined as the quotient of track length and track displacement).
In addition, the plasmonic cavity exhibits a large confinement factor, which is here defined as the ratio of the energy confined in the dielectric nanowire core of the cavity to the total energy of the cavity mode.
Behavior of rectangular concrete columns confined with FRP composites depends on several parameters, including unconfined concrete strength, confinement level, aspect ratio of cross-section (defined as the depth/width of the cross-section), and the sharpness of the section corners.
The factor F is primarily dictated by the degree of confinement of the guest molecules within the channels, defined as the ratio of the characteristic sizes of the guest molecules to that of the host channels.
Here, the quantum dots are defined as the semiconductor nanocrystals with the quantum confinement.
Confinement effectiveness is defined as f ' cc f ' co Open image in new window where f' cc = compressive strength of confined concrete, f' co = compressive strength of unconfined concrete.
The confinement potential may be defined as.
