In this example, the deformation of a console rod element connected with a built-in support at one end under temperature loading and the internal force value of a rod element with a fixed support at one end and a fixed support at the other end is calculated.
ideCAD Static Structural takes into account the loading situation caused by two different temperature changes and these temperature changes are considered separately.
Loading Model | Compared size | ideCAD Static | Manual solution | Percentage of error |
|---|---|---|---|---|
Model 1 - T1 | UZ (in) | 0.0013 | 0.0013 | 0% |
Model 1 - T2 | UZ (in) | 0.0026 | 0.0026 | 0% |
Model 2 - T1 | Axial pressure (mode) | 22.62 | 22.62 | 0% |
Model 2 - T2 | Axial pressure (mode) | 45.26 | 45.26 | 0% |

In Model 2, the concept of stiffness can be used to find the internal force value that occurs when temperature loading is applied. The extension stiffness of an element is calculated by the relation AE / L. In this case, using the values in Model 1 and the term extension stiffness, the value of the axial compressive force generated in the element;
