OS-V: 0100 Membrane with Hot-Spot
Test No. T1 OptiStruct examines the direct stress in y direction at a point D outside the hot-spot for linear thermos elastic analysis.
Figure 1. FE Model of with Boundary Conditions and Loadcases
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 |
