Temperature dependency example
This example of temperature dependency has the target of showing how the temperature dependency is applied on the model. The example will consists of an embedded beam on which a thermal load is applied. This will generate some stresses on the beam structure, which will be analyzed in order to prove if the behavior is correct.
In first, a thermal load of 873 K is applied on the beam. If the user looks up the value in the table, it will be noticeable that stresses must not be higher from 110.10 MPa:
A new Load group with a 873 K thermal load, besides a new Load Case, in which that load and the imposed boundary conditions are attached, are created.
After solving this model, stresses on X direction are visualized:
Stresses are constant all over the beam structure as it can be seen in the results list. Results will be visualized on the node 55, which corresponds to the central node.
So, as it wanted to be demonstrated, stresses have been taken just as they were required for the model. However, now, stresses will be changed in the table so as to see if CivilFEM comes up with the correct result:
Here it can be showed the table values as well as the chart of this modified branch. Stresses have been changed from the default value, 110.10 MPa, to 180 MPa. Taking into account that the thermal load will be the same (873 K) as well as the boundary conditions entered in the load case, new results about stresses on X direction will be compared.
Again, results list will be visualized on the node 55:
The value of the stress in that temperature had been risen on 70 MPa and stresses on the beam have reached to higher values from 110 MPa, but not exceeding 180 MPa. This example will help to the user in case of a bilinear temperature dependence is required.
