Abstract

The Summed up  idea of ​​manufacturing device (Multiaxial fatigue) is to benefit the identification of material properties which will be tested on this device when exposed to multiple axes loads ( Multiaxial loading ) where it can be through the device to know the age of fatigue of metals as well as can be identified on the growth notch and the stage of the break after exposure samples standard ( according to ASTM standards ) to carry bending loading only ( reversed bending ) multi axial loading (  bending with torsion ), and there are a lot of practical applications related to the test (Multiaxial fatigue failure ) such as determining the age of fatigue of the crankshaft  because it is exposed to double load ( bending with torsion )also a lot of poles motors and parts rotating in machines that are exposed to loads ( bending ) or( bending with torsion )in the case of loads that varies with time (non proportional loading ). It  can be through this device test different standard samples, whether the test columns or tubes, where this device is essential for use in mechanical engineering laboratories to keep pace with global technological developments, similar to other countries, which is a legitimate right as stated in one issue of the first paragraph. Legal paragraphs in industrial property guide the Central Agency for Standardization and Quality Control.
