摘　　要：研究了氧化铝陶瓷在常温下的两种疲劳特性及相应的寿命计算，通过三点弯曲疲劳实验得出氧化铝在不同疲劳幅值下的寿命图，表明静载荷对氧化铝具有与循环疲劳相似的疲劳效应，在高应力区甚至影响更大。Static and cyclic fatigue behavior of alumina at room temperature is investigated.The lifetimes for the two fatigue loads were measured in tests with different stress levels.It is revealed that static load has similar effect with cyclic fatigue on ceramics.Under high loading stress,the fatigue effcct of static loading is even greater than cyclic loading.
