| 中文摘要: |
| 20多年以来, 采用小型试件的小冲杆试验技术来测量在役设备材料的各种力学参数已经取得了很大进展, 这个方法已经用来确定材料的弹性模量、屈服强度、塑性性能、抗拉强度、 韧-脆转变温度、断裂韧度、蠕变性能和黏塑性性能等各种力学性能。由于从小冲杆试验的测量结果来确定材料的力学性能是一个反问题，因此，与此有关的反问题分析方法也得到了相应的发展。本文系统综述小冲杆试验的测量技术及从测量数据来确定材料弹塑性参数的各种经验方法和计算方法, 例如有限元分析和参数法、反向有限元法、有限元和反方法、反向识别和人工神经网络、有 |

| During overpassed 20 more years, as a kind of new experimental technology, small punch test for measuring small size specimens has been developed to evaluate the material mechanical properties of in-service equipments. It is already used to determinate the elastic modulus, yield stress, plastic properties, endurance strength, ductile-brittle transition temperature, fracture toughness, creep properties, plasto-viscous properties and so on. Because of the constitutive property assessment from the small punch test is an inverse problem, therefore the related analysis methods for the inverse problem have been developed greatly. This paper systematically provides an overview of recent developments in small punch test technology including empirical and computational methods for determining elasto-plastic parameters from the measured data of small punch test. The computational methods involve finite element and parameter method, inverse finite element procedure, finite element and inverse methodology, inverse identification based on artificial neural networks, finite element optimization, shape deformation and hybrid inverse procedure et al. |
