This paper presents a newly developed multiaxial high cycle fatigue testing machine to carry out the fatigue tests with high frequency under a non-proportional loading condition in which directions of principal stress and principal strain are changed in a cycle. The non-proportional loading can be practicable by a combination cyclic bending and reversed torsion. The maximum frequency is 50Hz which is approximately 25 times higher than that of the electrical servo controlled hydraulic multiaxial fatigue testing machine. An applicability of the developed testing machine is also discussed based on the obtained test results.
