METHOD AND DEVICE FOR MULTI-AXIAL FATIGUE TEST

摘要

PROBLEM TO BE SOLVED: To allow a fatigue test to be carry out in a uniform multi-axial strain condition without the need of a complex structure and an advanced control. SOLUTION: An annular support 2 concentric with a test piece 1 is disposed on one side of the test piece 1 with disk-like form, and a concentric annular force point 3 different from the support 2 is disposed on another side of the test piece 1. The fatigue test is carried out by supplying the load onto the force point 3 repeatedly.
