As the recent coronavirus outbreak has made painfully clear, the quantity and quality of our test efforts determine what defect rates we measure. If you don't test, or test poorly, you will discover few defects and may be tempted to draw the wrong conclusions about the quality of whatever it was that you were testing.

Probably the greatest proportion of failures of components or structures in service can be ascribed to failure by fatigue. This is a type of failure caused by the action of varying stresses below the short-term static tensile or torsional strength of the material.

<div class="htmlview paragraph">The people reports data on block program fatigue testing of a simple cantilever specimen with a stress concentration, the specimen being made of SAE 1530 steel. The various programs investigated were based on a normal distribution with a crest factor of 4 and were aimed at accelerating fatigue testing.</div> &

Tire Cord Fatigue and Fatigue Testing
Rubber Chemistry and Technology, 1957Abstract Examination of failed tires shows that fatigue failure mostly occurs on the inner plies, i.e., those subjected to compressive bending stress when the sidewall is bent. Continual flexing of the sidewall leads to a reduction of tensile strength of the cords until eventually the sidewall breaks up and the tire fails.

A new concept of “Cell Fatigue Test” is proposed. By reciprocating a cell across the throat of a micro channel repeatedly, the dynamic behavior of cell deformation is measured. We define a new index of fatigue life of cells as the number of reciprocatory motions leading to the prescribed recovery ratio.

The amount of technical information generated by a single fatigue test can vary from a terse noting of the cycles or time to the point when the specimen broke into two pieces, to the continuous observation of dislocation movement by means of television or movie camera.

So far, we have presented several of the elements of calculation necessary to analyse a range of idealised fretting contacts. They merely provide tools for determining the state of stress, strain and displacement, but do not, in themselves, permit production of initiation or crack propagation criteria, without extensive experimental data. The object of

Undoubtedly, the most fascinating development in the field of fatigue testing has been the recent growth of automation in this area. Fatigue tests by their very nature are very tedious to monitor continuously, and yet modern demands for complex signal simulation often do not permit one to use the elementary and easy-to-monitor signals so widely used in
