Low-cycle fatigue test results are useful in the areas of mechanical design as well as materials research and development, process and quality control, product performance, and failure analysis.

Strain-controlled fatigue testing has distinctive requirements on testing methods.

Results of the uniaxial tests on specimens of simple geometry can be applied to the design of components with notches or other complex shapes provided that the strains can be determined and multiaxial states of stress or strain and their gradients are correctly correlated with the uniaxial strain data.

Information about strain rate effects, relaxation behavior, and creep also may be available from these tests. Examination of the cyclic stress β€” strain curve and its comparison with monotonic stress β€” strain curves gives useful information regarding the cyclic stability of a material, for example, whether the values of hardness, yield strength, ultimate strength, strain-hardening exponent, and strength coefficient will increase, decrease, or remain unchanged that is, whether a material will harden, soften, or be stable because of cyclic plastic straining 1.

No restrictions are placed on environmental factors such as pressure, temperature, medium, humidity and others, provided they are controlled throughout the test, do not cause loss of or change in dimension with time, and are explained in the final report. In the case of variable amplitude or spectrum strain histories, cycle counting can be performed with Practice E No restrictions are placed on environmental factors such as temperature, pressure, humidity, medium, and others, provided they are controlled throughout the test, do not cause loss of or change in dimension with time, and are detailed in the data report.

Testing is done primarily under constant amplitude cycling and may contain interspersed hold times at repeated intervals. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: This standard works great for testing under various temperatures and strain rates.

Work Item s – proposed revisions of this standard. In particular, cyclic total strain should be measured and cyclic plastic strain should be determined. The satm may be applied to hourglass specimens, see bbut the user is cautioned about uncertainties in data analysis and interpretation.

In particular, cyclic total strain should be measured and cyclic plastic strain should be determined. Data analysis may not follow this test method in such cases. When testing for strain-controlled fatigue, it can be noted that it is influenced by the same variables that influence asmt fatigue.

Description Contact Us Low Cycle Asfm LCF testing is a growing area of materials testing, driven in particular by increasing demand from the aerospace, automotive and power generation industries. Subscribe to Instron News!

Concrete, Asphalt and Rock.

The presence d606 time-dependent inelastic strains during elevated temperature testing provides the opportunity to study the effects of these strains on fatigue life and on the cyclic stress-strain response of the material. To truly determine a time-independent strain the force would have to be applied instantaneously, which is not possible.

Historical Version s – view previous versions of standard. It is intended as a guide for fatigue testing performed in support of such activities as materials research and development, mechanical design, process and quality control, product performance, and failure analysis. Combining values from the two systems may result in non-conformance with the standard. They are commonly used in data correlations such as curves of cyclic stress or strain versus life and cyclic stress versus cyclic plastic strain obtained from hysteresis loops at some fraction often half of material life.

A related application area is Thermomechanical Fatigue TMF testing where mechanical loading of the test specimen is combined with simultaneous thermal cycling through induction heating and air cooling.

Note 1β€”The term inelastic is used e60 to refer to all nonelastic strains.

ASTM E606 – Strain-Controlled Fatigue Testing

Results of a strain-controlled fatigue test program may be used in the formulation of empirical relationships between the cyclic variables of stress, total strain, plastic strain, and fatigue life. Results can support such activities as materials research and development, mechanical design, process and quality control, product performance, and failure analysis.

Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 mm to 50 mm 0. The nature of strain-controlled fatigue imposes distinctive requirements on fatigue testing methods.

The test method may be adapted to guide testing for more general cases where strain or temperature may vary according to application specific histories.

While this practice is intended primarily for strain-controlled fatigue testing, some sections may provide useful information for force-controlled or stress-controlled testing.

ASTM E / EM – 12 Standard Test Method for Strain-Controlled Fatigue Testing

Strain-controlled fatigue is a phenomenon that is influenced by the same variables e6006 influence force-controlled fatigue. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

Information obtained from low-cycle fatigue testing may be an important element in the establishment of design criteria to protect against component failure by fatigue.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Static and fatigue forces up to 25 kN 5, lbf Frequency ratings up to Hz Servohydraulic Small, portable footprint.

No restrictions are placed on environmental factors such as temperature, pressure, humidity, medium, and others, provided they are controlled throughout the test, do not cause loss of or change in dimension with time, and are detailed in the data report. 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. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:.

ISO and ASTM E specify the standard practice for strain controlled fatigue testing, used for simulating mechanical loading into the plastic region. Differences in strain histories other than constant-amplitude alter fatigue life as compared with the constant amplitude results for example, periodic overstrains and block or spectrum histories. Work Item s – proposed revisions of this standard.
