Strain Controlled Tensile Fatigue E-N curves for Metals (Up to 2 Hz)
Tensile fatigue tests are performed per ASTM E606 at various strain levels to produce a cyclic strain versus cycles to failure curve (E-N curve). Each strain level is repeated 3 times to account for variability. The default parameters for this test are 30 Hz, R=0.1 with expected failures from 100 to 100000 cycles at 23°C with specimen machining and polishing included. Prices vary by the parameters so please call if your parameters differ from these.
This test can be performed as low as -55°C or as high as 1200°C. Frequencies, number of cycles, and stress ratio can be varied.

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 <105) 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.
