本WRC公告是两个公告系列中的第二个，涵盖了安全壳内爆炸诱导压力荷载安全设计的断裂安全和疲劳设计标准。两个公告系列中的第一个于2002年12月作为WRC公告477出版。这两份公告供美国机械工程师学会（ASME）锅炉及压力容器规范委员会在制定承受高能、爆炸诱导压力载荷的安全壳安全设计规范时参考。本公告为HSLA-100钢制安全壳的断裂安全和疲劳裂纹扩展充分性设计提供了技术依据和理由。尽管本报告专门论述了LANL安全壳的设计，但本文采用的方法和标准可扩展到其他容器几何形状（即:。 e、 圆柱、椭球或球面壳、圆锥体等）和更复杂的容器系统（即圆柱到圆柱的交叉点等）。最后，由于这些实验产生的爆炸产物和碎片会产生有害物质，因此本文所述的标准适用于高能炸药（HE）爆炸诱导加载事件的一次性应用。从财务角度来看，对这些容器进行改造以供进一步使用（即多次HE事件）是禁止的。因此，安全壳设计必须充分利用材料的延展性和断裂韧性。本文采用的技术方法是断裂安全设计，由海军研究实验室在20世纪70年代开发，基于美国材料试验学会（ASTM）的动态撕裂试验能量（DTTE）- 批准的程序（ASTM E 604）。这项工作发表在WRC公告186上。然而，断裂安全设计方法由其他数据（即夏比、J-R）和附录中提出的高级断裂力学程序进一步补充。

This WRC Bulletin, the second of the two Bulletin series, covers the fracture-safe and fatigue design criteria for the safe design of detonation-induced pressure loading in containment vessels. The first of the two Bulletin series was published in December 2002 as WRC Bulletin 477. These two Bulletins are intended for use by the American Society of Mechanical Engineers (ASME) Boiler & Pressure Vessel Code Committee for their consideration in developing code rules for the safe design of containment vessel subjected to high-energy, detonation-induced, pressure loading.This bulletin provides the technical basis and justification for a fracture-safe and fatigue crack-growth adequacy design of HSLA-100 steel containment vessels. Although this report specifically addresses the LANL containment vessel design, the methodology and criteria applied herein may be extended to other vessel geometries (i.e., cylinders, ellipsoidal or torispherical shells, cones, etc.) and more complex vessel systems (i.e., cylinder-to-cylinder intersections, etc.). Lastly, because the explosion products and debris from these experiments produce hazardous materials, the criteria described in this paper are for a single-use application of a high-explosive (HE) detonation-induced loading event. The reconstitution of these vessels for further use, i.e., multiple HE events, becomes prohibitive from a financial standpoint. As such, the containment design must incorporate full advantage of the material's ductility and fracture toughness.The technical approach utilized herein is that of Fracture Safe Design, which was developed by the Naval Research Laboratory in the 1970's and is based upon the Dynamic Tear Test Energy (DTTE), an ASTM-approved procedure (ASTM E 604). This work was published as WRC Bulletin 186. However, the Fracture Safe Design approach is further supplemented by other data (i.e., Charpy, J-R) and advanced fracture mechanics procedures presented in the Appendices.
