Stress–strain (SS) curves are essential for understanding material properties, such as yield and ultimate tensile strength. However, traditional destructive tensile testing has constraints in terms of material reusability and the detection of local behavioral changes. This study proposes two novel techniques: (1) nondestructive SS curve estimation using ultrasound and (2) 3D visualization of SS curves, termed the ‘3D SS curved surface’. We predicted the local SS curves using the Ramberg-Osgood model by deriving the key input parameters from automated ultrasonic measurements. Consequently, a 3D SS curved surface was constructed by combining multiple SS curves estimated from each local area through ultrasonic scanning and by introducing the scanning direction as the third axis in addition to the stress and strain axes. The experimental 3D SS curved surfaces of the locally damaged samples indicated novel observations that were undetectable using conventional tensile testing. The proposed techniques show significant potential for applications in materials science, engineering, manufacturing, and reliability assessment.

使用超声和 Ramberg-Osgood 模型进行三维应力-应变曲线估计和可视化:一种无损的材料表征方法
应力-应变 (SS) 曲线对于了解材料特性(例如屈服强度和极限抗拉强度)至关重要。然而,传统的破坏性拉伸测试在材料可重用性和局部行为变化检测方面存在限制。本研究提出了两种新技术:(1) 使用超声进行无损 SS 曲线估计和 (2) SS 曲线的 3D 可视化,称为“3D SS 曲面”。我们通过从自动超声测量中得出关键输入参数,使用 Ramberg-Osgood 模型预测了局部 SS 曲线。因此,通过超声扫描将每个局部区域估计的多条 SS 曲线组合在一起,并将扫描方向作为应力轴和应变轴之外的第三轴,构建了一个 3D SS 曲面。局部受损样品的实验性 3D SS 曲面表明了使用传统拉伸测试无法检测到的新观察结果。所提出的技术在材料科学、工程、制造和可靠性评估方面显示出巨大的应用潜力。
