Standard Rainflow File Format

2018-08-24
CURRENT
J2623_201808
This SAE Standard provides a definition of a rainflow file format. This type of simple text file would contain all relevant information about the rainflow cycle content of a time history. Included information are Comments, Signal Range, Signal Mean, Number of Cycles, Signal Maximum, Signal Minimum. Rainflow cycle counting has become the most accepted procedure for identifying material fatigue relevant cycles in complex variable amplitude load time histories. The cycle counting methods account for the effects of material plasticity and material memory of prior deformation, and the resulting compressed history information is used by durability analysts to estimate the effects of a given service or test history.

Strain-Life Fatigue Data File Format

2018-08-24
CURRENT
J2649_201808
SAE data file format for exchanging controlled periodic overload data. The object of this SAE Standard is to provide a simple, common methodology for exchanging the data from periodic overload fatigue tests. These tests consist of a single large fatigue cycle followed by a larger number of smaller cycles. The overloads are fully reversed fatigue cycles while the smaller cycles share a common mean and amplitude.

Multi-Dimensional Thermal Properties of Insulated Heat Shield Material Systems

2018-08-24
CURRENT
J2609_201808
This test method measures the system material properties of an insulated formed heat shield under in-vehicle conditions. While the material properties of the individual components can often be determined via existing test methods, the system properties of the entire composite is typically much harder to ascertain (especially for multi-layer shields). System material properties include thermal conductivity in the lateral or in-plane (x) direction, thermal conductivity through the thickness or perpendicular (y), surface emissivity on the top and bottom sides of the shield and specific heat of the shield material.

Technical Report on Low Cycle Fatigue Properties Ferrous and Non-Ferrous Materials

2018-08-24
CURRENT
J1099_201808
Information that provides design guidance in avoiding fatigue failures is outlined in this SAE Information Report. Of necessity, this report is brief, but it does provide a basis for approaching complex fatigue problems. Information presented here can be used in preliminary design estimates of fatigue life, the selection of materials and the analysis of service load and/or strain data. The data presented are for the “low cycle” or strain-controlled methods for predicting fatigue behavior. Note that these methods may not be appropriate for materials with internal defects, such as cast irons, which exhibit different tension and compression stress-strain behavior.

Helical Springs: Specification Check Lists

2016-08-02
CURRENT
J1122_201608
The following SAE Recommended Practice furnishes sample forms for helical compression, extension and torsion springs to provide a uniform method for specifying design information. It is not necessary to fill in all the data, but sufficient information must be supplied to fully describe the part and to satisfy the requirements of its application. For detailed information, see “Design and Application of Helical and Spiral Springs - SAE HS 795”, also “Helical Compression and Extension Spring Terminology - SAE J1121”. Both of these documents use SI (metric) Units in accordance with the provisions of SAE TSB 003, as does SAE J1122. Here, however, the U.S. Customary Units (in, lb, psi) have been added in parentheses after each SI Unit for the convenience of the user who must furnish specifications on a project where all requirements are listed in non-metric terms.

Helical Compression and Extension Spring Terminology

2016-08-02
CURRENT
J1121_201608
The following recommended practice has been developed to assist engineers and designers in the preparation of specifications for the major types of helical compression and extension springs. It is restricted to a concise presentation of items which will promote an adequate understanding between spring manufacturer and spring user of the major practical requirements in the finished spring. Closer tolerances are obtainable where greater accuracy is required and the increased cost is justified. For the basic concepts underlying the spring design and for many of the details, see the SAE Information Report MANUAL ON DESIGN AND APPLICATION OF HELICAL AND SPIRAL SPRINGS, SAE HS 795, which is available from SAE Headquarters in Warrendale, PA 15096. A uniform method for specifying design information is shown in the TYPICAL DESIGN CHECK LISTS FOR HELICAL SPRINGS, SAE J1122.
