... compression on contact stress of sealing structure of the casing coupling section is numerically analyzed. The results show that the combined loads of axial tension, internal and external pressure difference and extruding force will make contact stress of the sealing structure of casing coupling change...

...-material constant; i (i=1,2,3)-principal strain of three directions. Properties of the sealing discs used in the analysis are listed in Table 2. The inner radius of pipe in the FE model is 300mm. Contact stress between pig and pipe wall is one of the most important input parameters used in the simulation...

... and compares these with the crossed-wire contact stresses developed between wire layers. The stress concentration occurring between contacting wires is treated as an "equivalent notch" and the fatigue analysis follows the conventional practice of designing machine components. Model results are compared...
