Abstract

In the contribution at hand, the quadratic Hill yield function is extended to a finite strain, multiplicative kinematic framework. Furthermore, it is expanded by a novel combination of linear and exponential hardening. The formulation is derived in a consistent manner. Subsequently, the capabilities to model Ti-6Al-4V in a realistic manner are demonstrated, considering the anisotropy in plastic material behavior, which is induced by additive manufacturing. Therefore, different tensile tests from the literature are simulated, and a validation is carried out. Finally, the significance of the anisotropy is demonstrated in a numerical example. The maximal force obtained in the simulation is shown to be significantly different, if the building direction is considered.

利用二次Hill屈服函数对Ti-6Al-4V进行乘法有限应变运动学建模

在手边的贡献，二次希尔屈服函数被扩展到一个有限应变，乘运动学框架。此外，它是由线性和指数硬化的新颖组合展开。该配方是以一致的方式推导出来的。随后，考虑到增材制造引起的塑性材料行为的各向异性，证明了以现实方式模拟Ti-6Al-4V的能力。因此，模拟了文献中不同的拉伸试验，并进行了验证。最后，通过数值算例说明了各向异性的重要性。在考虑建筑物方向的情况下，模拟得到的最大力有很大的不同。

期刊介绍： The International Journal of Engineering Science is not limited to a specific aspect of science and engineering but is instead devoted to a wide range of subfields in the engineering sciences. While it encourages a broad spectrum of contribution in the engineering sciences, its core interest lies in issues concerning material modeling and response. Articles of interdisciplinary nature are particularly welcome. The primary goal of the new editors is to maintain high quality of publications. There will be a commitment to expediting the time taken for the publication of the papers. The articles that are sent for reviews will have names of the authors deleted with a view towards enhancing the objectivity and fairness of the review process. Articles that are devoted to the purely mathematical aspects without a discussion of the physical implications of the results or the consideration of specific examples are discouraged. Articles concerning material science should not be limited merely to a description and recording of observations but should contain theoretical or quantitative discussion of the results.
