|Thus, once we aim to the earth-friendly society,
it naturally lets us try to use everything which consists of metal products
importantly for a lomg time.
However, there is an question"Is it really possible to use them safely?".
There are still few results in the materials science field regarding to
It is because it takes enormous time.
Actually, it needs extremely long time to perform a fatigue test in the
giga-cycle regime(more than 107times).
Nevertheless, we will never achieve the earth-friendly safety society unless
the fatigue test in the giga-cycle regime.
Thereupon, a multi-type fatigue testing machine has been developed.
Our Dual Spindle Rotating Benfing fatigue testing machine "GIGA QUAD"
made it possible to perform tests for 4specimens simultaneously, which
means very speedy!!
