Abstract

Anisotropy is a key feature of the plastic behavior of aluminum alloy sheets. Significant research efforts have been dedicated during the past few decades to characterize and model this behavior. Advanced anisotropic yield criteria are available today in the scientific literature. This article reviews the most important yield criteria, in historical order, with an emphasis on the models particularly adapted to aluminum alloys. Along with the mathematical description, illustrations of their performance are provided together with the parameter identification procedure and the required input data. The mechanical parameters that describe plastic anisotropy are also summarized. The relevance of the available models for practical applications is analyzed, and guidance is provided for the selection and aware use of these yield criteria in engineering.
铝合金薄板的各向异性屈服准则
各向异性是铝合金板材塑性行为的一个重要特征。在过去的几十年里,人们进行了大量的研究工作来描述和模拟这种行为。先进的各向异性屈服标准在今天的科学文献中是可用的。本文回顾了最重要的屈服标准,按历史顺序,重点是模型特别适用于铝合金。除了数学描述外,还提供了它们的性能示例,以及参数识别过程和所需的输入数据。总结了描述塑性各向异性的力学参数。分析了现有模型与实际应用的相关性,为工程中屈服准则的选择和合理使用提供了指导。
