Fatigue testing machine diagram.

Materials fatigue performance is commonly characterized by an s n curve also known as a wöhler curve this is often plotted with the cyclic stress s against the cycles to failure n on a logarithmic scale s n curves are derived from tests on samples of the material to be characterized often called coupons or specimens where a regular sinusoidal stress is applied by a testing machine. Fatigue testing is a specialised form of mechanical testing that is performed by applying cyclic loading to a coupon or structure. He designed the machine to test railroad car axles and investigate axle brake failures. Fatigue tests are used on a range components from coupons through to full size test.

Electrodynamic testing machines are used to determine the durability of materials and components in the finite life fatigue and high cycle fatigue ranges. Fatigue strength is thus of very great significance in machine design. Rotatory bending machine the purpose of the rotating bar bending fatigue test is to determine the bending fatigue strength properties under rotating load. Balaji fatigue testing machine capacity 200 kgcmthe machine is designed determining the fatigue properties of metals and alloys reverse bending cantilever type machine where the specimen is subjected to rotation at 2800 rpm with both ends held firmly between the gripping chucks with weights suspended through a lever.

The principles upon which that machine was developed still apply today.
