Cumulative settlement is one of the primary potential detrimental aspects of rocking foundations. It has been well documented that if the factor of safety against bearing failure is not very large (e.g., less than five or so), settlement can become significant. A series of footings of different shapes were subject to lateral slow cyclic loading on the centrifuge to study the effect of shape on ...

The monotonic and cyclic deformation behavior of ultrafine-grained metastable austenitic steel AISI 304L, produced by severe plastic deformation, was investigated. Under monotonic loading, the martensitic phase transformation in the ultrafine-grained state is strongly favored. Under cyclic loading, the martensitic transformation behavior is similar to the coarse-grained condition, but the cycli...

Background and Aim: Oral bacteria can proliferate in the implant-abutment interface (IAI) and cause inflammation in the peri-implant tissues and adjacent bone. This study aimed to assess the effect of zirconia and titanium abutments on the microleakage of the IAI under oblique cyclic loading conditions. Materials and Methods: In this in-vitro study, 12 implant-abutment assemblies with zirconia...

This paper was aimed at highlighting the impact of loading waveforms on cyclic liquefaction resistance sand. The test specimens were reclaimed by dry tamping method with Hostun 31 sand, and density sand matrix controlled to be 0.70. Three sets undrained triaxial tests performed altering as follows: triangular, sine rectangular waves. waveform experimentally observed axial stress applied. Under ...

Cyclic compressive loading tests were carried out on bovine femoral bones at body temperature (37 °C), with varying mean stresses (-55 to -80 MPa) and loading frequencies (0.5-5 Hz). At various times, the cyclic loading was interrupted to carry out high-energy X-ray scattering measurements of the internal strains developing in the hydroxyapatite (HAP) platelets and the collagen fibrils. The res...

BACKGROUND The cementation of crowns to dental implant abutments is an accepted form of crown retention that requires consideration of the properties of available cements within the applied clinical context. Dental luting agents are exposed to a number of stressors that may reduce crown retention in vivo, not the least of which is occlusal loading. This study investigated the influence of compr...
