This paper presents the results of high temperature strain-range controlled low cycle fatigue tests a laser powder bead fused AlSi10Mg alloy. Following stress relief (2hrs at 300 ℃), two cyclic loading waveforms (standard triangular and dwell-type trapezoidal waveforms) three temperatures (100 ℃, 250 ℃ 400 ℃) were applied to investigate both mechanical response related microstructural changes t...

this paper describes a series of laboratory model tests on strip footings supported on unreinforced and geogrid-reinforced sand with an inside void. the footing is subjected to a combination of static and cyclic loading. the influence of various parameters including the embedment depth of the void, the number of reinforcement layers, and the amplitude of cyclic load were studied. the results sh...

This paper assesses the ability of Adjustable Localisation Operator (ALO) method to predict influence residual stresses on fatigue behaviour notched components. Different initial stress states are introduced into specimens, which then tested under cyclic loadings in a range 103 105 cycles. Experimental comparisons with initially stress-free specimens have shown how tensile reduce life repeated ...

The irregularity of peak and valley stress values loading histories is the main impediment for accurate fatigue-based structural health monitoring. Since available fatigue material data (e.g., S-N curves) have been derived by cyclic tests, existing damage accumulation models can be implemented on structures under loading, cycle-counting algorithms transformation a spectrum into an equivalent on...

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...
