比较了粗化组织的“伪弹性”合金Ti-6Al-4V和“塑性”材料铜的循环应力-应变行为和S/N行为。根据Freudenthal最近提出的观点，注意到这两种材料之间的重要区别。这些差异包括裂纹起裂方式、鲍辛格效应强度以及长寿命疲劳数据所在的宏观屈服以下水平。
The cyclic stress-strain behavior and the S/N behavior of a “pseudo-elastic” alloy, Ti-6Al-4V of coarsened microstructure and of a “plastic” material, copper, are compared. In accord with views recently put forth by Freudenthal, important differences are noted between these two types of materials. These differences include the mode of crack initiation, the intensity of the Bauschinger effect, and the level below macroscopic yield at which long-life fatigue data lie.
