Description / Abstract:
This SAE Aerospace Recommended Practice (ARP) establishes
flexure test procedures to determine and classify the fatigue
strengths of reconnectable or permanent hydraulic tube joints.
The procedure is intended for conducting flexure tests of
fittings and joints for hydraulic tubing materials such as AMS 5561
(21Cr-6Ni-9Mn) steel or AMS 4944 (3AL-2.5V) titanium.
A mean stress is applied by holding system pressure in the
specimens and flexing in a rotary or planar bending test
machine.
