Strain Controlled Fatigue of Metallic Materials (Up to 2 Hz)
A single tensile fatigue specimens is loaded to a peak total strain and unloaded at a given frequency. This process of loading and unloading is repeated a state of failure occurs (either due to rupture, significant softening, or accumulation of plastic strain).
This test can be performed as low as -55°C or as high as 1200°C. Frequencies, number of cycles, and strain ratio can effect the pricing.

Strain-controlled fatigue can be an important consideration in the design of industrial products. It is important for situations in which components or portions of components undergo either mechanically or thermally induced cyclic plastic strains that cause failure within relatively few (that is, approximately <10E5) cycles. Information obtained from strain-controlled fatigue testing may be an important element in the establishment of design criteria to protect against component failure by fatigue.
