Temperature Displacement in Abaqus
Temperature Displacement in Abaqus
(OP)
I have a very thin part that I need to perform a thermal displacement on in Abaqus. I need to find the displacement of a point on the part due to temperature increase. I know the initial and final temperatures and the mechanical boundary conditions (the edges of the part are mechanically fixed).
I am familiar with most CAD softwares as well as a few FEA programs. However, Abaqus is the only program available to me.
Is there an easier way to perform this analysis in abaqus other than using the sequentially coupled thermal stress analysis?

A simpler way is to just specify the temperatures at nodes, usually when you have a uniform distribution, or some other simple form. If you're using shell elements remember that you have the variables NT11..NT15 to specify temperatures for (depending on the number of section points through the thickness). Otherwise you'll specify a temperature at point 1 with 0 degrees at all other points through the section.

-define the thermal expansion properties of the material
-define the initial temperature field
-define the displacement boundary conditions
-prescribe variation of temperature field and other mechanical loads.
