Sentence examples for material fatigue tests from inspiring English sources

Axial unnotched strain-controlled material fatigue tests provided the required cyclic material properties.

After the quantification of the Secondary Dendrite Arm Spacing (SDAS) and grain size of the material, fatigue tests are analyzed through fractographic Scanning Electron Microscope (SEM) observations in order to reveal the type of defects at the origin of the failure.

To determine the model parameters for the cast iron materials, fatigue tests are performed under combined loading and crack growth is measured at room temperature using the replica technique.

In this paper, our primary concern was to develop an experimental methodology for detecting processes that accompany the evolution of defects in the material during fatigue test on the ultrasonic testing machine.

This paper aims to investigate damage mechanisms developing within the material during fatigue test in order to understand the origin of this phenomenon.

Such a reduction has been associated with the fracture and partial detachment of the coating from the substrate along the substrate-deposit interface and the reduction in the area of the load-carrying segments of the composite material during fatigue testing.

The preliminary experiments clearly demonstrated that these methods can be used to monitor the processes of evolution of the material structure during fatigue tests on the ultrasonic testing machine and to estimate the duration of the final stage, at which the specimen reaches its endurance limit.

In order to develop an appropriate fatigue damage parameter of the rubber material, load-controlled fatigue tests were conducted using three-dimensional dumbbell specimens at different levels of mean load.

Validation is presented by way of application to composite material fatigue fracture toughness tests; Double Cantilever Beam for Mode I, End Notch Flexure for mode II and Mixed Mode Bending for the mixed mode case.

On this special testing machines must be effectively realised high cycle fatigue tests of material and also full scale parts, because presumed life — cycle of railway axles is till thirty years.

Local hysteresis measurement is suitable for fatigue tests of inhomogeneous materials or materials which have inhomogeneous damage process.
