Methods of mechanical testing of metals

Расчеты и испытания на прочность в машиностроении. Методы механических испытаний металлов. Методы испытаний на усталость

Status: Effective - Supersedes. The limitation of effectiveness has been lifted: Protocol No. 2-92 of the IGU dated 05.10.92 (IUS 2-1993)

The standard establishes methods of testing samples of metals and alloys for fatigue: in tension - compression, bending and torsion; with symmetric and asymmetric cycles of stress or deformation, measured according to a simple periodic law with constant parameters; in the presence and absence of stress concentration; at normal, high and low temperatures; in the presence or absence of an aggressive environment; in a high and low cycle elastic and elastoplastic region. The standard does not establish special test methods for samples used in testing the strength of highly stressed structures.

Стандарт устанавливает методы испытаний образцов металлов и сплавов на усталость: при растяжении - сжатии, изгибе и кручении; при симметричных и асимметричных циклах напряжений или деформаций, измеряющихся по простому периодическому закону с постоянными параметрами; при наличии и отсутствии концентрации напряжений; при нормальной, повышенной и пониженной температурах; при наличии или отсутствии агрессивной среды; в много- и малоцикловой упругой и упругопластической области. Стандарт не устанавливает специальные методы испытаний образцов, используемые при отработке прочности высоконапряженных конструкций.
