How is a temperature variation load modeled?
Question:How is a temperature variation load modeled?
This FAQ addresses the modeling options of Advance Design for different situations where the structural elements are subjected to temperature variations:
2. The element is subjected to a temperature variation on the local y or/and z axes.
To highlight the differences between the two situations, we will treat each example separately.
For the first example, we define a cantilever.
We must first define the reference temperature of the system. We either set it when creating a new model or we can modify it during modeling from the "Assumptions - Structure..." menu.
Next we create a load case family from the temperature variations.
Element elongation from temperature variation is:
2. Modeling the temperature loads by gradient defining:
Element deformation from temperature variation is:
Where are as shown in the following figure:
For modeling, the user should enter the values both for the temperature and also for the gradients.
