基于国产A508-Ⅲ钢的单轴拉伸测试,构建了Ramberg-Osgood力学本构模型和GTN(Gurson-Tvergaard-Needleman)细观损伤模型,并对模型参数进行了标定,开展了不同温度下小尺寸CT(1/6CT)试样的断裂韧性测试,采用规则化方法计算得到裂纹扩展阻力曲线(J-R曲线),分析了测试温度对材料断裂性能的影响。结果表明,随着温度从-100℃度降低至-130℃,断口韧窝区的宽度由43μm缩减至10μm,平均韧窝尺寸从0.3μm缩小至0.05μm,材料的塑性变形能力随着温度的降低而脆化。基于构建的力学本构模型和GTN细观损伤模型,采用有限元法分析了1/6CT试样从裂纹萌生、扩展至失效断裂的过程。结果表明,J-R曲线随着温度的下降而降低,断裂韧性(J_(IC)值)和裂纹扩展量(Δa)的降幅分别为43%和3%,相对误差不超过5%。这表明,基于GTN细观损伤模型的数值方法是研究小尺寸CT试样断裂行为的一种简便、有效的方法。

为了克服拉伸样品尺寸减小所带来的尺寸效应的影响,本文对A508-Ⅲ钢小尺寸样品的拉伸行为进行了研究。通过改变A508-Ⅲ钢的热处理温度制备了不同晶粒尺寸和样品厚度的小尺寸样品,进行了小尺寸样品的室温拉伸测试,分析了晶粒尺寸和样品厚度对小尺寸样品拉伸力学性能的影响,并揭示了其潜在的拉伸尺寸效应机理。结果表明,由于小尺寸样品厚度和晶粒尺寸的变化,导致其拉伸力学性能表现出明显的尺寸效应;通过引入综合表征样品特征尺寸和晶粒尺寸效应的影响参数,构建了考虑尺寸效应的Swift力学本构模型;采用有限元辅助测试方法确定了小尺寸样品的延性损伤演变参数,数值与实验结果误差小于3%;基于建立的力学本构模型,利用有限元方法预测了小尺寸样品的拉伸力学性能,构建了其屈服强度与抗拉强度的归一化模型,以期为小尺寸样品的工程应用提供借鉴。
