    Thermal Expansion of a Cylinder

    Thanks, at this point the cylinder is solid (with a few surface features machined into it, but for arguments sake lets say it's smooth). Outside temperature is uniform when in operation. The ends are restrained by a spring loaded seal, so there is an applied load but it can expand. Thanks for...

    Thermal Expansion of a Cylinder

    My applogies if this is a repost, but the search function isn't working. I know the most accurate way to calculate the change in diameter of a cylinder due to thermal expansion is to use an FEA, but I don't have access to software at the moment. I want to know how good an approximation I will...

    I'm relatively new to Ansys and working in a small office, I have no experts to refer to. I have an automotive valve train part I'm trying to do a combined thermal-structural analysis on. The problem I have is that I need to varry the temperature loading with time. I know how to use tables to...
