摘要

液化天然气(LNG)设施内存储容器的爆炸分析需要严格的有限元分析(FEA)。本文详细介绍了LNG储罐在爆炸荷载作用下的非线性动力分析方法。利用市售有限元软件Abaqus的显式动态求解器进行分析。LNG储罐的有限元模型包括静流体压力和内压力。本构材料模型包括应变率相关的弹塑性材料效应。根据有限元分析的结果，提出了在蒸汽云爆炸(VCE)下保持容器结构完整性的安全实践建议。

Damage Modeling of Storage Vessels in Liquefied Natural Gas Facilities due to Flammable Vapor Cloud Explosion

Blast analysis of a storage container inside a liquefied natural gas (LNG) facility needs rigorous finite element analysis (FEA). This paper presents a detailed method of nonlinear dynamic analysis of LNG storage vessels subjected to blast load. The explicit dynamic solver of the commercially available FEA software Abaqus is used to perform the analysis. The finite element models of the LNG storage tanks include the static fluid pressure and internal pressure. Constitutive material models include strain-rate dependent elastic-plastic material effects. Based on the results of FEA, recommendations are made for safe practice of maintaining the structural integrity of vessels subjected to vapor cloud explosion (VCE).

期刊介绍： The Practice Periodical on Structural Design and Construction publishes articles about practical solutions to structural design problems and construction challenges of interest to practitioners. Articles may be of any length. Those reporting on small and medium-sized projects will be welcomed. Photographs are desirable; graphs, tables, and lengthy formulas are discouraged. The editors are not interested in what researchers have to say to one another; although articles must be technically sound, the overriding question in the editors" minds when considering a submission is whether the article will be of interest to a significant number of practicing engineers and contractors.
