Experimental Investigation on Behavior of Single-Helix Anchor in Sand Subjected to Uplift Cyclic Loading

open access: yesJournal of Marine Science and Engineering, 2022
Helical anchors have been widely used in geotechnical engineering due to their large uplift resistance. However, the current knowledge of the cyclic performance of helical anchors is still insufficient.

Dynamic Response of Cement–Fly Ash Mixed Pile Composite Foundation Under Wave Load

open access: yesFrontiers in Earth Science, 2022
CFMPs (cement and fly ash mixing piles) are used to reinforce fly ash foundation to solve the problem of a large amount of fly ash accumulation in coastal areas.

The Effect of Fiber Orientation and Stress Ratio on the Crack Growth Behavior of Fiber Metal Laminates (FMLs)

open access: yesInternational Journal of Technology, 2018
The crack growth behavior of fiber metal laminates (FMLs) with fiber orientations of 90°/0° and 45°/45° to load direction was investigated with varying stress ratios of the cyclic constant load.

Analysis of a rapid load test on an instrumented bored pile in clay [PDF]

open access: yes, 2006
Rapid load testing methods for piled foundations are generally easier and quicker to mobilise than classic static tests, and are less complex to analyse than dynamic load tests.

Numerical Investigation of the Influence of the Drill String Vibration Cyclic Loads on the Development of the Wellbore Natural Fracture

open access: yesEnergies, 2021
Wellbore instability is one of the most serious issues faced in the drilling process. During drilling operations, the cyclic loads applied on the fractured formation progressively modify the initial parameters (i.e., length and width) of the fractured ...

Investigations on influences of Engineered Cementitious Composites (ECC) on pull-out properties of studs in steel-concrete composite bridge

open access: yesCase Studies in Construction Materials, 2023
Stud plays an important role in the connection of steel-concrete composite bridge (SCCB). The stud is under pull-out load in the negative moment zone of SCCB.

Ratchet analysis of structures under a generalised cyclic load history

open access: yes, 2014
This paper introduces a new approach based upon the Linear Matching Method in order to obtain the ratchet limit of structures subjected to an arbitrary thermo-mechanical load history. This method varies from the traditional Linear Matching Method ratchet

Inconsistent effect of dynamic load waveform on macro- and micro-scale responses of ballast bed characterized in individual cycle: a numerical study

open access: yesRailway Engineering Science, 2023
Cyclic load is widely adopted in laboratory to simulate the effect of train load on ballast bed. The effectiveness of such load equivalence is usually testified by having similar results of key concerns of ballast bed, such as deformation or stiffness ...

Influence of cyclic loading on load-to-failure of different ceramic CAD-CAM implant-supported single crowns.

open access: yes, 2023
PURPOSE To compare the load to failure values of different ceramic CAD/CAM implant crown materials with drilled screw access holes with and without cyclic loading applied.

The effect of varying loading directions and loading levels on crack growth at 2D- and 3D-mixed-mode-loadings [PDF]

open access: yesFracture and Structural Integrity, 2016
While product’s operation the loading situation commonly changes. The local loading situation on an existing crack then can shift to a combined loading, composed of mode I, mode II and mode III, and consequently influence the product’s durability ...
