Static Stress Analysis

Static Stress Analysis

Static Stress Analysis

(OP)
If a object is under a load at a high temperature, how do you include the temperature affect over the tensile and yield strength in the static stress analysis?

RE: Static Stress Analysis

James08,

What FEA package are you using?

Generally, you have a reference temperature defined in your material information as well as a thermal expansion coefficient.  When you input your element information, you assign a nodal or elemental temperature.  The FEA package then takes the difference between your element temperature and your material reference temperature, multiplies this by your thermal expansion and adds the resultant displacement to the displacement determined by your physical loads of your static stress model.  The combined displacement is then used to calculate stress...you can usually output thermal stress separately from stress due to physical loads and then you can show the combined version.
