Hello,<\/p>\n

I am trying to build an interference fit simulation between two steel cylinders in a 2D plane stress or plane strain model of a 30 degres pie slice. <\/p>\n

I tried to follow in details all the recommendations in the links below:
\/forum\/forums\/topic\/basic-interference-fit\/
\/forum\/forums\/topic\/interference-fit-pressure\/
https:\/\/youtu.be\/5jH2Ox6-YkU<\/p>\n

The problem is that I am getting a FEA contact pressure of 83 MPa, whereas the theoretical value is 75 MPa ! (same materials: E=200 000 MPa, vu=0.3, dimensions given in below Figure).<\/p>\n

Could you help me solving this issue ? any recommendations ?<\/p>\n

You can find below the links to the Ansys Archive .wbpz file <\/p>\n

–> Model1.wbpz<\/a><\/p>\n

I also tried to build the same model in a 2D axisymetric view, but I also get 83 MPa and not 73 MPa <\/p>\n

–> Model2.wbpz<\/a><\/p>\n

Thanks in advance,<\/p>\n

Sami<\/p>\n
