聚合物ABS的应力疲劳性能与交变应力频率的关系

Polymer ABS stress fatigue properties and alternating stress frequency

在疲劳实验的基础上研究聚合物ABS在不同频率的对称循环交变应力作用下的应力疲劳性能,并给出ABS的有限疲劳寿命(Nf=5×105)的疲劳强度与交变应力频率的关系。

Based on fatigue experiment of polymer ABS in different frequency cyclic stress under the action of stress fatigue performance, And finite fatigue life is ABS （Nf = 5 × 105 ） fatigue strength and frequency of the al- ternating stress.
