钢结构的裂纹尖端的状态对结构的断裂影响很大,是钢材断裂分析和设计中研究的重点。由于一般构件的几何形状和荷载状态复杂,难于对裂纹尖端的应力和应变状态得到理论的结果,因此有限元的计算方法非常重要。介绍ANSYS软件在钢结构断裂分析的运用。使用ANSYS有限元软件对各种断裂模型进行计算,获得了各种因素对钢结构断裂的影响规律。
The crack tip state of the steel structure has a great influence on the fracture of the structure, which is the focus of the research on the fracture analysis and design of the steel. The finite element method is very important due to the complexity of the geometry and load of common components and the difficulty of obtaining theoretical results on the stress and strain state at the crack tip. Describe the use of ANSYS software in the fracture analysis of steel structures. ANSYS finite element software was used to calculate various fracture models, and the influence of various factors on the fracture of steel structure was obtained.
