[Editor: Chen Feng] (continued from 495) times, stop the test,<a href="http://www.stivaliuggboots.com" target="_blank">ugg stivali</a>, remove the model law by blowing the crack length measured 50cm. Cone test model based submarine connection cylinder shell at the weld toe surface cracks exist, the initial crack size is: C. A 2.5mm, a. A 0.1mm. Weld toe residual stress is taken as 0.3a a 193MPa. In the absence of high-strength steel in the fatigue growth performance parameters,<a href="http://www.stivaliuggboots.com" target="_blank">ugg italia</a>, so Richards and other proposed use of a 200 ~ 900MPa for steel and welding the fatigue crack propagation rate: da a 5.932 × 10 ・ (△ K) \. (4) Where: The fracture toughness of high strength steel for the K. value of a 85MPa, the compressive stress of a lamb to take one by one one by one === 227.5MPa, bending stress take a 806.7MPa. calculated fatigue life is 5321 times, when the crack length is 81.14mm, the crack depth is 7.466mm. calculation errors compared with the experimental results less initial defects in the determination of .7 Conclusion There are many methods, including the lower limit of sensitivity of detection equipment , the engineering definition of initiation phase of the weld classification standards, testing the statistical distribution of defects. The initial flaw size submarine using a single method can not be reasonably determined to be in various ways, based on a comprehensive assessment to determine the final The initial crack size: c. a 2.5mm, a. a 0.1mm. by model test,<a href="http://www.stivaliuggboots.com" target="_blank">ugg prezzo</a>, the initial size to better reflect the initial defects on structural fatigue life, indicating that the initial set defects is a reasonable start.
