分析和实验研究将在此进行 research. 实验测试将在伺服控制的 具有拉伸、扭转和内压载荷的加载装置 测试薄壁管的装置。 将进行测量， 确定非比例应变历史的应力响应， 多晶延性金属，其中应变诱导塑性 产生各向异性。 然后将这些数据应用于制定 预测这种反应的本构关系。 这种组合 实验和分析研究具有很好的扩展潜力 有限变形分析域的情况下， 变形与各向异性特征的耦合 地方

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.
