摘要

最近有报道称，Zr-2.5Nb压力管（PT）材料的最大载荷断裂韧性（Jmax）几乎不受裂纹扩展误差的影响（Δa）。为了检查Δa测量中Jmax对误差的敏感性，假设Zr-2.5Nb和zircaloy-2 PT材料以及四种不同钢在最大载荷（Pmax）之前没有裂纹扩展，计算了Jmax。对于所有6种材料，当载荷达到Pmax时，假设无裂纹扩展（Jo）的J值与基于实测Δa （Jc）计算的J值几乎相同。基于J的变形理论，建立了一个解析判据来检验Jmax对Δamax误差的敏感性。使用测量的Δamax （Jcmax）计算的Jmax与使用假设无裂纹扩展（Jomax）计算的Jmax之间建立了良好的相关性。对于断裂韧性在15-1200 kJ/m2范围内、裂纹扩展可达2.3 mm的大范围材料进行断裂试验时，利用建立的JIC和Jmax之间的关系计算Jmax和/或JIC，而不使用任何裂纹扩展测量系统，这些结果将非常有用。这对于在辐照材料等断裂试验中很难测量裂纹扩展的情况是非常有用的。

Sensitivity analysis of error in crack length measurement on Jmax

Recently it was reported that maximum load fracture toughness (J_max) of Zr-2.5Nb pressure tube (PT) material was practically unaffected by error in crack growth (Δa) measurement. To check the sensitivity of the J_max to error in Δa measurement, the J_max was calculated assuming no crack growth up to the maximum load (P_max) for Zr-2.5Nb and zircaloy-2 PT material as well as four different steels. For all six materials, for load up to the P_max, the J values calculated assuming no crack growth (J_o) were practically same as that calculated based on the measured Δa (J_c). Based on deformation theory of J, an analytic criterion was developed to check the sensitivity of the J_max to the error in Δa_max. An excellent correlation was established between J_max calculated using the measured Δa_max (J_cmax) and J_max calculated using assuming no crack growth (J_omax). These findings will be very useful to calculate J_max and/or and then J_IC using established relationship between J_IC and J_max without any crack growth measurement system during fracture test for wide range of materials with fracture toughness in the range of 15–1200 kJ/m² and crack extension up to 2.3 mm. This is very useful for the conditions where it is very difficult to measure the crack growth during fracture tests such as irradiated material.

期刊介绍： Pressure vessel engineering technology is of importance in many branches of industry. This journal publishes the latest research results and related information on all its associated aspects, with particular emphasis on the structural integrity assessment, maintenance and life extension of pressurised process engineering plants. The anticipated coverage of the International Journal of Pressure Vessels and Piping ranges from simple mass-produced pressure vessels to large custom-built vessels and tanks. Pressure vessels technology is a developing field, and contributions on the following topics will therefore be welcome: • Pressure vessel engineering • Structural integrity assessment • Design methods • Codes and standards • Fabrication and welding • Materials properties requirements • Inspection and quality management • Maintenance and life extension • Ageing and environmental effects • Life management Of particular importance are papers covering aspects of significant practical application which could lead to major improvements in economy, reliability and useful life. While most accepted papers represent the results of original applied research, critical reviews of topical interest by world-leading experts will also appear from time to time. International Journal of Pressure Vessels and Piping is indispensable reading for engineering professionals involved in the energy, petrochemicals, process plant, transport, aerospace and related industries; for manufacturers of pressure vessels and ancillary equipment; and for academics pursuing research in these areas.
