Failure Analysis of a Hydraulic Manifold Plate
Practical Metallography, 2015Abstract Massive forming requires the use of large costly production facilities. Their degree of utilization plays an important role in price calculation. Direct costs are incurred by disruptions in the production process. Those disruptions should therefore be avoided whenever possible.

Hydraulic torque wrench adapter failure analysis
Engineering Failure Analysis, 2019Flaw appearance, crack occurrence and consequential failures are of serious concern in any mechanical design process. Once failed, parts can be analyzed in order to determine the causes of failures. Therefore, failure analysis proves to be a valuable tool in design improvement.

Consequences to the Patient in the Event of Hydraulic Unit Failure
Stereotactic and Functional Neurosurgery, 1993An anomalous hot spot, which occurs when the motion of the Leksell Gamma Unit is halted, was investigated. A series of measurements indicated that the source of this hot spot is the focusing property of the primary collimator. It was determined that this effect is unlikely to result in serious consequences to the patient, even in the event of failure ...

Hydraulic failure by underseepage of dykes and levees
ce/papers, 2018AbstractThe increase in frequency, magnitude and duration of floods during the past decades has become an outstanding challenge to geotechnical engineering. When dykes or levees do not have a cut‐off wall fully penetrating the aquifer, underseepage may occur during high river levels.

Calculating the Probability of Failure of a Hydraulic System
Australasian Journal of Water Resources, 2002This paper illustrates a simple, accurate and efficient method of estimating the probability of failure of a hydraulic system. The proposed method requires the same information as that of conventional methods. It does not require one to estimate or assume the probability density function of the performance function, describing the behaviour of the ...

The research on failure issues for a hydraulic system
2012 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering, 2012The hydraulic systems are widely used in industry, but they would inevitably give rise to some failures. Firstly, this paper describes some hydraulic system failures in a reliability test. Secondly, it makes a detailed analysis for the reasons of failure. Lastly, some corresponding solutions are given for the different failures.

Failure analysis of cavitation in a hydraulic loader
Engineering Failure Analysis, 2016Abstract Cavitation is one of the major failure modes in hydraulic loaders. The failure mechanism is related to damage induced by cavitation at the working surface. Moreover, the vibrations caused by cavitation reduce the efficiency of the unit and lead to irregular output.

Failure analysis of hydraulic turbine shaft
Engineering Failure Analysis, 2012Abstract This paper describes the analysis of major failure of 28 MW horizontal hydro turbine shaft. The analysis of load carrying capacity of critical radius and fractography analysis are presented. Special emphasize is on metallurgical failure analysis of in-service crack initiation. The analysis of stresses is obtained by the finite element method

Hydraulic failures of earthen dams and embankments
Innovative Infrastructure Solutions, 2019The problem of dam failures is of great importance as it has devastating impact upon humankind and the environment. This review highlights the hydraulic failure of earthen dams and embankments, emphasizing on the piping and overtopping phenomena. Piping failures are mostly attributed to the uncontrolled seepage or the absence of suitable zonation of ...

Hydraulic Fracturing: Coulomb Failure in Shale Fracture
82nd EAGE Annual Conference & Exhibition, 2021Summary The hydraulic fracturing (HF) technique has been widely used for unconventional reservoirs with extremely low permeability. Natural fractures are a ubiquitous feature of unconventional reservoir and due to low matrix permeability, HF generally intersects natural fractures leading to relatively complex geometrical system enables fluid and ...
