# SS-V: 4000 Thermally Loaded Support Structure

Test No. VTL01 Find stresses in a support stucture with a rigid beam, steel, and copper bars subjected to load and uniform temperature rise.

## Definition

The steel bar material properties are:

**Properties****Value**- Modulus of Elasticity
- 30.e+6 psi
- Coefficient of thermal expansion
- 70.e-7 in/in-F
- Copper bar correspondingly
- 16.e+6 psi and 92.e-7 in/in-F

Total load applied to the rigid beam is 4000 lbf with a temperature change of 10
degrees Fahrenheit. The bars have cross-sectional area 0.1 inch^{2} and
length 20 inch.

Structure components are simulated by solids. Dimensions of the support bars are 20 x 0.5 x 0.2 inch, rigid beam are 12 x 1 x 1 inch. The rods are equally spaced at a distance of 5 inch. Rigid beam is simulated as an absolutely rigid body.

## Results

Stress | Ref Solution | SimSolid | % Difference |
---|---|---|---|

Steel [psi] | 19695.0 | 19697 | 0.01% |

Copper [psi] | 10152 | 10151 | -0.01% |
