摘要
非比例加载下，应力、应变的求解是个困难的问题。通过修正内蕴时间尺度，本文用内时本构理论给出了计算循环稳定应力、应变滞环的简便方法。
It is difficult for calculations of stress/strain under nonproportional loading. Modified Endochronic time scale, the paper presents a simple calculation of cyclic stable stress/strain hysteresis loop by Endochronic constitutive theory under nonproportional loading. It is requisite for lowcycle fatigue life prediction under nonproportional loading.
