Deformation and failure of the tank bottom

2009-03-13View Original

Thread Content

Question: According to clause 15.3.6.3 of JB/T4735 \"Steel Welded Atmospheric Pressure Vessels\", after the welding of the tank bottom, the depth of local uneven deformation shall not be greater than 2% of the deformation length, and shall also not exceed 50 mm. How to understand it? Assuming the bottom plate experiences a bulging deformation of 40 mm over a length of 2000 mm, will it not tear under stress?
