本文介绍了确定具有塑性予应变板材后继屈服条件的实验方法。铝合金板LY12～M12的实验研究表明:随着塑性予应变的增加,将依次出现各向同性强化、运动强化以及组合强化。
This paper presents an experimental method to determine the subsequent yield conditions for plastic-to-strain plates. Experimental studies on the LY12 ~ M12 aluminum alloy plates show that the isotropic strengthening, the kinematic strengthening and the combination strengthening will occur in turn as the plastic pre-strain increases.
