Abstract

The small punch test technique was developed in the USA in the 1980 s, followed shortly by Japan and introduced to Europe in the 1990 s. CEN organized Workshop 21 to summarize more than ten years of research results and formulate the first technical guidelines CWA 15627. The specification work for European standard started in 2015 and the first European standard EN-10371 was published in 2022. The EN-10371 standardized the specimen size and test apparatus. It also specifies the test procedure and characteristic parameters for small punch test (SP) and small punch creep test (SPC). Nine annexes allows estimation of the values normally obtained using classical standard size uniaxial or fracture mechanics specimens. In order to make the standard perfect and usable, the standard working group proposed a five year “standard follow up” project in 2019. Responding to the proposed project, authors carefully re-examined the specification, and found some shortcomings in the standard. Proposals are put forward to improve the current methodology and extend the standard scope to include the latest development.

对 EN-10371 标准的意见和标准后续建议

CEN 组织了第 21 次研讨会，总结了十多年的研究成果，并制定了第一份技术指南 CWA 15627。欧洲标准的规范工作始于 2015 年，首个欧洲标准 EN-10371 于 2022 年发布。EN-10371 规范了试样尺寸和测试仪器。它还规定了小冲压试验（SP）和小冲压蠕变试验（SPC）的试验程序和特征参数。九个附件允许估算通常使用经典标准尺寸单轴或断裂力学试样获得的数值。为了使该标准更加完善和实用，标准工作组建议在 2019 年开展一个为期五年的 "标准跟进 "项目。为响应该建议项目，作者们仔细重新审查了规范，发现了标准中的一些不足之处。提出了改进现行方法和扩大标准范围的建议，以纳入最新发展。

期刊介绍： Theoretical and Applied Fracture Mechanics'' aims & scopes have been re-designed to cover both the theoretical, applied, and numerical aspects associated with those cracking related phenomena taking place, at a micro-, meso-, and macroscopic level, in materials/components/structures of any kind. The journal aims to cover the cracking/mechanical behaviour of materials/components/structures in those situations involving both time-independent and time-dependent system of external forces/moments (such as, for instance, quasi-static, impulsive, impact, blasting, creep, contact, and fatigue loading). Since, under the above circumstances, the mechanical behaviour of cracked materials/components/structures is also affected by the environmental conditions, the journal would consider also those theoretical/experimental research works investigating the effect of external variables such as, for instance, the effect of corrosive environments as well as of high/low-temperature.
