【Abstract】 Analysis for the cause of bringing the penetration axial cracks in the steam generator is made. The stresses and stress intensity factor are analyzed numerically by three dimensional finite element method. The influence of residual stress is reached. The safety evaluation for the steam generator in leak before break condition is presented.更多还原
