Therefore in this example the burst pressure would be in the 27–34 bar(g) range. (It is difficult to predict this value accurately because so few vessels actually fail, so there is not much field data.) Increased temperatures rapidly reduce the strength of the steel. For example, the ...
Per-grain and neighbourhood stress interactions during deformation of a ferritic steel obtained using three-dimensional X-ray diffraction Three-dimensional X-ray diffraction (3DXRD) has been used to measure, in-situ, the evolution of 1800 \\sim 1800 grains in a single phase low carbon ferri......
The fracture condition is determined so that the fracture stress ascertained in a 4-point-bending experiment is defined as the maximum bearable tensile stress. The statistical theory according to Weibull is applied to transform this fracture stress onto the type of stress occurring during the cooling...
