Abstract

This study focuses on developing a constitutive model to describe the dynamic plasticity and fracture behavior of arc-melted cladding for remanufacturing wind turbine gears. By combining quasi-static tensile tests and Split Hopkinson Tension Bar (SHTB) experiments, the research investigates the static and dynamic properties of Wire Arc Additive Manufacturing (WAAM) alloy cladding under various strain rates and high temperatures. Results reveal strain hardening, strain rate hardening, and thermal softening effects, leading to the establishment of Johnson-Cook(J-C) plasticity and failure models. Finite element simulations validate the model, achieving an absolute average relative error(AARE) of 8.670% and an R value of 0.9449, confirming the model’s accuracy and reliability for predicting the alloy's dynamic behavior in remanufacturing applications.

电弧增材制造高强钢熔覆层的静动态本构关系

本研究的重点是建立一个本构模型来描述风电齿轮再制造电弧熔覆层的动态塑性和断裂行为。通过准静态拉伸试验和劈裂霍普金森拉伸杆（SHTB）试验相结合，研究了电弧增材制造（WAAM）合金包层在不同应变速率和高温下的静态和动态性能。结果显示了应变硬化、应变速率硬化和热软化效应，从而建立了Johnson-Cook（J-C）塑性和破坏模型。有限元仿真验证了该模型的正确性，其绝对平均相对误差（AARE）为8.670%，R值为0.9449，验证了该模型在再制造应用中预测合金动态行为的准确性和可靠性。

期刊介绍： Mechanics Research Communications publishes, as rapidly as possible, peer-reviewed manuscripts of high standards but restricted length. It aims to provide: • a fast means of communication • an exchange of ideas among workers in mechanics • an effective method of bringing new results quickly to the public • an informal vehicle for the discussion • of ideas that may still be in the formative stages The field of Mechanics will be understood to encompass the behavior of continua, fluids, solids, particles and their mixtures. Submissions must contain a strong, novel contribution to the field of mechanics, and ideally should be focused on current issues in the field involving theoretical, experimental and/or applied research, preferably within the broad expertise encompassed by the Board of Associate Editors. Deviations from these areas should be discussed in advance with the Editor-in-Chief.
