Abstract

The purpose of this work is to study the effect of anisotropic plasticity on the micro-deep drawing of the 304 stainless steel foils through a combination of experimental testing and numerical modeling. A phenomenological anisotropic model, with the Yld2004-18p yield function, is used to model the anisotropic plasticity deformation of the material. Based on the miniature tensile experimental data and Voce's hardening law, the coefficients in the Yld2004-18p function were calibrated. The FE modelling was implemented using ABAQUS to simulate the micro-deep drawing experiments. The wall thickness and height of the cylindrical cup obtained by the simulation have shown to be reasonably close to the experimental values, and the distribution of ears is the same as the experimental results. It has shown that the Yld2004-18p anisotropic yield function can accurately describe the anisotropic behavior of 304 stainless steel foils during the micro-deep drawing process.

304 薄膜微拉伸过程中的各向异性塑性变形：实验和数值研究

摘要本文旨在通过实验测试和数值建模相结合的方法，研究各向异性塑性对 304 不锈钢薄片微拉伸的影响。采用 Yld2004-18p 屈服函数的各向异性现象学模型来模拟材料的各向异性塑性变形。根据微型拉伸实验数据和 Voce 的硬化定律，对 Yld2004-18p 函数中的系数进行了校准。使用 ABAQUS 建立了有限元模型，以模拟微型拉伸实验。结果表明，模拟得到的圆柱杯壁厚和高度与实验值相当接近，杯耳分布与实验结果相同。结果表明，Yld2004-18p 各向异性屈服函数能准确描述 304 不锈钢箔在微拉伸过程中的各向异性行为。

期刊介绍： The Journal publishes and disseminates original research in the field of material forming. The research should constitute major achievements in the understanding, modeling or simulation of material forming processes. In this respect ‘forming’ implies a deliberate deformation of material. The journal establishes a platform of communication between engineers and scientists, covering all forming processes, including sheet forming, bulk forming, powder forming, forming in near-melt conditions (injection moulding, thixoforming, film blowing etc.), micro-forming, hydro-forming, thermo-forming, incremental forming etc. Other manufacturing technologies like machining and cutting can be included if the focus of the work is on plastic deformations. All materials (metals, ceramics, polymers, composites, glass, wood, fibre reinforced materials, materials in food processing, biomaterials, nano-materials, shape memory alloys etc.) and approaches (micro-macro modelling, thermo-mechanical modelling, numerical simulation including new and advanced numerical strategies, experimental analysis, inverse analysis, model identification, optimization, design and control of forming tools and machines, wear and friction, mechanical behavior and formability of materials etc.) are concerned.
