Cyclic behavior of a two-span RC beam built with plain reinforcing bars [PDF]

open access: yes, 2011
Reinforced concrete structural elements lacking appropriate seismic detailing and built with plain reinforcing bars, and subjected to cyclic loads like the ones induced by earthquakes, are particularly sensitive to the bond-slip mechanism.

Experimental and Simulation Study of Low-Velocity Impact on Glass Fiber Composite Laminates with Reinforcing Shape Memory Alloys at Different Layer Positions

open access: yesApplied Sciences, 2018
The effects of shape memory alloy (SMA) wires on the damage behavior of glass fibers/epoxy resin composite laminates for the case of low-velocity impact are investigated experimentally and numerically.

Nonlocal Damage Mechanics [PDF]

open access: yesRevue Européenne de Génie Civil, 2020
ABSTRACT This paper starts with an overview of models that can provide an objective description of highly localized inelastic deformation. Basic ideas behind the integral and differential formulations of nonlocal models are explained using a simple isotropic damage model as a typical example.

Mechanisms of Biliary Damage

open access: yesJournal of Cell Death, 2010
Bile duct damage is present in virtually all cholangiopathies, which share the biliary epithelial cells (i.e. cholangiocytes) as a common pathogenic target. Cholangiocyte cell death largely occurs through the process of apoptosis. In this review, we will summarize the mechanisms through which biliary damage occurs in a variety of animal and in vitro ...

Acoustic Emission and Digital Image Correlation-Based Study for Early Damage Identification in Sandwich Structures

open access: yesApplied Sciences
Understanding the deterioration and predominant damage mechanisms of structures is highly relevant, especially for safety-critical components. Non-Destructive Testing (NDT) plays a crucial role in assessing and monitoring their integrity by evaluating ...

Data-Driven Diagnostics of Mechanism and Source of Sustained Oscillations [PDF]

open access: yes, 2015
Sustained oscillations observed in power systems can damage equipment, degrade the power quality and increase the risks of cascading blackouts. There are several mechanisms that can give rise to oscillations, each requiring different countermeasure to ...
