And the relation between plasticzonesize and load frequency is only qualitatively analyzed up to now.
而对载荷频率与塑性区域尺寸之间关系仅有定性描述。

The plasticzonesize of the crack tip is relative to three dimensional constraint which depends upon not only the plate thickness but also the load and the material property.
裂纹尖端塑性区的大小与其三维约束状态有关,而三维约束状态不仅与板厚还与外载荷、材料性质有关。
