Combined Analytical and Experimental Investigation of Strain-Induced Anisotropy in the Plastic Deformation of Metals

本研究将进行分析和实验研究。将在伺服控制加载装置中进行实验测试，该加载装置具有拉伸、扭转和内压加载装置，以测试薄壁管。将进行测量，以确定在多晶延性金属中产生应变诱导塑性各向异性的非比例应变历史的应力响应。然后，这些数据将被应用于建立预测这种响应的本构关系。这种实验研究和分析研究相结合的方法很有可能将有限变形分析的领域扩展到变形与各向异性特征发生耦合的情况。

Analytical and experimental investigations will be carried out in this research. Experimental tests will be made in a servo-controlled loading device with tension, torsion, and internal pressure loading arrangements to test thin-walled tubes. Measurements will be made to determine the stress response to non-proportional straining history in polycrystalline ductile metal in which strain-induced plastic anisotropy is generated. The data will then be applied to formulate constitutive relations which predict such response. This combination of experimental and analytical research has a good potential to extend the domain of finite deformations analysis to cases in which the coupling of the deformation with anisotropic characteristics take place.
