Influence of post-cyclic loading on hemic peat
… many years, in road design as an example, static loading method was applied in road designed by considering soil shear strength through static load and do not take into account the vehicular dynamic loading and shear strength thereafter. This fact is related to the shear strength of peat soil …

Response of reinforced concrete to reverse cyclic loading
… cracked reinforced concrete subjected to reverse cyclic loading with particular emphasize on the contribution from tensile stresses in cracked concrete. An iterative strain compatibility approach using a nonlinear bond stress-slip relationship was implemented into a computer program. The program …

Hysteretic response of articular cartilage to cyclic loading
This research investigates the phenomenon of hysteresis in cartilage experimentally. The presence of a hysteresis loop in cartilage indicates energy loss, thereby signaling degradation of cartilage leading to osteoarthritis. Although hysteresis in ligaments and tendons has been studied to a great …

Durability of Polymer /Metal Interfaces Under Cyclic Loading
… Using this newly developed technique, effects of loading mode and frequency were studied. The fatigue resistance was found to increase with the mode II component and was expressed as a function of the KII/K I ratio. A strong frequency effect was observed for the subcritical crack growth along the …

Analytical model for reinforced concrete under cyclic loading
The finite element method is a very powerful computational technique for computer solution of complex problems. Its formulation can include both geometrical and material nonlinearities at the element level. Unfortunately, the validity of the nonlinear finite element analysis is often limited by the …

Centrifuge modelling of railway embankments under static and cyclic loading
… This however does not take into account the cyclic loading aspect the embankment is subjected to. Physical modelling in a centrifuge is one of the most effective tools available to a geotechnical engineer. Using the typical designed slopes currently used on the coal export line, the failure …

Cracking of reinforced concrete structural walls subjected to cyclic loading
… a significant size effect and being subjected to loading regimes that are representative of what would be expected in real structures. The advanced research capabilities in the Network for Earthquake Engineering Simulation (NEES) facility at the University of Illinois at Urbana-Champaign make it …

Constitutive modelling of the behaviour of clays under cyclic loading
… theory to model the behaviour of a clay under cyclic loading. The modelling must be based on an understanding of the soil response and the critical state theory provides a description of the soil response which then be formulated in terms of plasticity theory. A literature review showed that …

Behavior of Post-Tensioning Systems Subjected to Inelastic Cyclic Loading
… residual building drifts following seismic loading. As a result of the PT strands large elastic deformation capability, they have been proven to work efficiently in these types of systems. Although typically designed to stay elastic during design basis earthquake events, strands may …

Cyclic Loading Effects on Craniofacial Strain and Sutural Growth in Pigs
… skull is also lacking. Purpose: 1. To develop a loading system capable of reliably delivering cyclic loads to the nasofrontal suture (NFS), 2. To explore strain transmission resulting from cyclic loading of the NFS both ex vivo and in vivo and 3. To characterize the effects of cyclic loading on …

Self-healing strain-hardening cementitious composites (SH2CC) for cyclic loading environments
Cyclic loading is ubiquitous and frequently encountered in various infrastructure. However, the widely used construction material, concrete, is inherently brittle and could be poor at sustaining cyclic stress (especially those involving tensile stress). Although reinforcement can help avoid …

Investigation of long-term cyclic loading effects on initially intact cartilage
… long-term applications of an indentation loading protocol, which does not induce any observable damage over a single short-term application, can result in surface damage. The damage can be associated with an increase in the GAG release and decrease in the tissue nominal equilibrium …

Fiber fracture in continuous-fiber reinforced composite materials during cyclic loading
… between those devices and the material, under cyclic conditions. This investigation presents the findings of a fiber-based investigation of unidirectional composite material systems. In particular, a unidirectional graphite/epoxy system was studied, and the influence of applied load level on …

Stress-strain behaviour of granular soils under monotonic and cyclic loading conditions
… behaviour of granular soils under monotonic and cyclic loading conditions and small lateral strains was studied in this work. A simple cubic triaxial apparatus (SCTA), originally developed at Leeds University for monotonic stress-strain studies of sand under controlled and small lateral strains, …
