摘要

棘轮是低周疲劳载荷的第二种破坏模式，在这种情况下，每个循环都会产生塑性应变。由于循环硬化过程的复杂性，构件变形难以精确估计。为了研究变形，必须首先确定各种类型的硬化规则。本文介绍了利用Abaqus软件确定复合硬化参数的方法。本文利用了前人研究的API-5L X80实验数据。最后，对不同输入条件下的非线性运动硬化选择进行了分析。

Combined hardening parameters of high strength steel under low cycle fatigue

Ratcheting is a second failure mode in low cycle fatigue loading where plastic strain accumulates in each cycle. It is difficult to precisely estimate component deformation due to the complexities of cyclic hardening. In order to study the deformation, all types of hardening rules must be determined priorly. In this study, the determination procedures of combined hardening parameters are presented using Abaqus software. The experiment data of API-5L X80 from the past research have been utilized. Lastly, the different inputs of non-linear kinematic hardening choices are analyzed and presented.

期刊介绍： Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
