    Thermal Expansion and Poisson ratio

    Hi Ashu28, I just realized that uploading more than one file does not work. Therefore, I zipped everything into one file. Danielhttp://files.engineering.com/getfile.aspx?folder=54e567ce-6d48-4073-be62-dc0a85db7045&file=Example.zip

    Thermal Expansion and Poisson ratio

    Hi Ashu28, unfortunately I do no more have these calculations I. But I prepared an example, OneCyl.cae, for you. I try to upload it. OneCyl is a simple cylinder that get heated from 0 to 100 degree and threfore expands. Points to pay attention: -Element type: Coupled Temperature Displacement...

    Thermal Expansion and Poisson ratio

    I tried the direct way first, but had troubles with convergence. That is why I tried thermal expansion. Can I find an example of an interference fit somewhere? cheers, Daniel

    Thermal Expansion and Poisson ratio

    I finally succeeded,thank's a lot for your help. One last question. I did the thermal expansion because I did not succeed in modeling an interference fit. It works now, but it looks like a rather clumsy way for doing it. Is there not a more elegant solution? And why is it so difficult to model...

    Thermal Expansion and Poisson ratio

    note that the expansion is: 1.3e-3, not 1e-3!!!! I think I found the reason for the extensive expansion. In a 2dim Model, Abaqus seems to keep the third dimension constant! Due to the thermal expansion, the 3.dim would expand by 0.001xlength. With a length of 1 this would give 0.001. Keeping it...

    Thermal Expansion and Poisson ratio

    If I simulate the thermal expansion of a square sheet with Abaqus, I receive an expansion that is too large by the Poisson number. E.g. a simple set up: A 1x1 square sheet, with a thermal expansion coefficient of 1E-6 and a temperature increase of 1000 degree should expand by 1E-3. Instead I...
