ASTM E covers axial force controlled fatigue tests of metallic materials in the fatigue regime where strains are predominately elastic, both at initial loading and throughout the test. ASTM E is limited to the fatigue testing of axial unnotched and notched specimens subjected to a constant amplitude, periodic forcing function in air at room temperature.

Place the specimen securely in the grips of the testing machine. Specimens can be round or flat. Take care to adjust the specimen symmetrically to distribute the load uniformly over the cross section.

This avoids complications that prevent the true strength of the material from being evaluated. Take care to properly align the specimen. Start the machine. Continue sinusoidal cycles to failure. Record the load at the time of failure. By means of our fatigue testing expertise and modular product design, we will help find the solution that is right for you.

ASTM E466 Load Controlled Constant Amplitude Fatigue Tests of Metals

Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. Touchstone is experienced in the performance of fatigue testing in almost every material system and at a wide variety of temperatures from cryogenic to over ? Machining methods and techniques can strongly influence the fatigue life of a material. Proper machining techniques prevent the introduction of stress risers or crack initiation sites. Touchstone is experienced in fatigue specimen preparation to comply with strict sample preparation requirements, including surface finish of the machined sample. This knowledge and care provides the most meaningful and best possible high cycle fatigue life results.

ASTM E466 – Force Controller Constant Amplitude Axial Fatigue Testing of Metallic Materials

Additive manufacturing is growing into a practical, applicable means of production. As pioneers of this medium continue to refine the process and develop its capabilities, manufacturers increasingly employ it to make a variety of specialized products. In response to the expansion of this manufacturing tool, Applied Technical Services has expanded our testing scope to provide for the needs of the clients who rely on additive manufacturing. Our mechanical testing lab can measure several performance properties like hardness and tensile strength using an array of methods. We determine how metallic samples created through additive manufacturing respond to material fatigue by testing it to the standard of ASTM E
