摘要
在考虑容器局部互扰裂纹(短裂纹群)对主裂纹(主导裂纹)扩展速率的影响后,精确计算了容器剩余疲劳寿命。通过实例验算,该方法适合工程要求。
The residual fatigue life of pressure vessels was accurately calculated in consideration of the influence of the local interactive cracks ( short cracks) on the expansion speed of the major crack (dominant crack). The method was suitable for practical engineering.
