In this work, we performed four variations of cyclic load testing on four groups of modules using the LoadSpot tool. Each group first underwent 50 thermal cycles (TC50), 10 humidity-freeze cycles (HF10), and a 2400 Pa static load. Then, the baseline group was tested using standard cyclic loading conditions from IEC 62782, another with double the ...

Cyclic loading in knee ligament injuries
The American Journal of Sports Medicine, 1980The effect of cyclic loading on knee ligaments was studied both in vivo and in vitro. The compliance of the medial collateral ligaments of athletes participating in hockey, basketball, soc cer, and downhill skiing was determined by using a specially built machine. Tests were conducted before and after partici pation in the various sports.

Damage of Marble from Cyclic Loading
Journal of Materials in Civil Engineering, 2001The behavior of marble was investigated to evaluate the damage and failure mechanisms produced from cyclic loading. Approximately 100 cycles of increasing load steps, representing low cycle fatigue, were imposed on beams in three and four-point bending. Damage was recorded through an array of strain gauges and an interferometric technique that provided

Crown retention and cyclic loading (in vitro)
European Journal of Oral Sciences, 1993Cast gold crowns were luted on extracted and prepared human teeth with zinc phosphate cement and subjected to a fatigue test by cyclic loading. The correlation between crown retention and three retention variables was determined by the fatigue test. The results show that the smallest convergence angle tested, 20°, gave better retention than did angles ...

The Behavior of Salem Limestone in Cyclic Loading
Society of Petroleum Engineers Journal, 1974Abstract Specimens of Salem limestone were loaded cyclically at a frequency of 2 cycles/sec in uniaxial cyclic compression, tension, and compression-tension. The number of cycles to failure, maximum deformation for each cycle, and load-deformation hysteresis loops were recorded.

Pile Load Tests: Cyclic Loads and Varying Load Rates
Journal of the Geotechnical Engineering Division, 1981Two series of axial load tests were performed on four 14-in. (356-mm) diam, open-end, steel pipe piles at an interval of about 320 days. Pile lengths of 40 ft or 50 ft (12.2 or 15.2 m) were installed below conductors driven to depths ranging from 115 ft to 320 ft (35 m to 98 m) into a strong underconsolidated clay. Each pile was subjected to as many as

Cyclic Pressuremeter Tests for Cyclic Lateral Loads
Offshore Technology Conference, 1984ABSTRACT The results of thirteen cyclic pressuremeter tests performed in hand augured holes on a stiff clay are presented. These tests show that the slope of the unload-reload loop stabilizes after only a few cycles but that the strain at the peak of the cycle continues to cumulate long after the slope of the loop ...
