The goal was to come up with a nanometal that was strong enough, hard enough and "supple" enough to resist fatiguefailure and wear in advanced applications.
我们的目标是提供足够强度和硬度，又兼具足够抵御疲破坏的纳米材质，以使其能够与高级应用相借合。

Fatiguefailure results from accumulation of cracks of deformation pro - cess of material.
疲劳破坏是材料在变形过程中产生的裂纹积累。

The dynamic effects due to vibration should be taken into account by the designer if fatiguefailure is to be avoided.
