Benchmark Model
Quarter model is considered and Quad4 elements with the specific mesh specifications are used for model building. The hotspot area is maintained at a temperature 100 °C.
The material properties are:
- Hot-spot Area
- Young's Modulus
- 100 x 103 MPa
- Poisson's Ratio
- 0.3
- Coefficient of Thermal Expansion
- Remaining Area
- 1 x 10-5/°C
- Young's modulus
- 100 x 103 MPa
- Poisson's ratio
- 0.3
- Coefficient of thermal expansion
- 0.0
Linear Static Analysis Results
All results are normalized with the target value (50 MPa).
| Quadrilateral Shells | Direct Stress in y Direction at a Point D, Outside Hot-spot (MPa) | Normalized with the Target Value |
|---|---|---|
| Quad4 | 47.26 | 1.057977147 |
| 45.51 | 1.098659635 |
