An analysis of steel construction brittle fracture This paper researches the mechanical properties and fracture properties with experiments at low temperature, and analyzes the influences of stress status on fracture mode, and finally proposes the applicable brittle fracture prevention design method.
本文对结构钢材低温力学性能和断裂韧度性能进行了试验研究和计算分析，分析应力状态对构件脆性破坏的影响，进而提出了钢结构低温冷脆的实用设计方法。
With the fast developing of national air industry, the statue of high-strength materials becoming more and more important. However, the strength of the material increased the ability of to resistance crack propagation is weak, so low stress brittle fracture phenomenon is very serious.
随着我国航空航天的快速发展，高强度材料的地他日益重要。然而随着材料强度的逐渐升高反而使材料抵抗裂纹扩展的能力在逐渐变弱，所以导致低应力脆断现象很严重。
