Hello everyone i have an issue with my thermal analysis.<\/p>\n

i’ve done a thermal expansion analysis with ansys workbench and i’ve displayed many informations like stress, displacement etc… <\/p>\n

But in my case only the displacements are interesting. The issue come’s when i try to check the result in  Woekbench with a handed calculation ( i find differents values with the hand calculation ( 25µm) and with workbench i find (33µm)). For the handed calculation i’ve used the formula :Δ<\/span><\/span>L<\/span><\/span>=<\/span><\/span>a<\/span><\/span>⋅<\/span><\/span>L<\/span><\/span><\/span>1<\/span><\/span><\/span><\/span>⋅<\/span><\/span>(<\/span><\/span>T<\/span><\/span><\/span>2<\/span><\/span><\/span><\/span>−<\/span><\/span>T<\/span><\/span><\/span>1<\/span><\/span><\/span><\/span>) <\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

the system is just a roll represented by a quart of a circle<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n
