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
Coefficient of Thermal Expansion
Remaining Area
1 x 10-5/°C
Young's modulus
100 x 103 MPa
Poisson's ratio
Coefficient of thermal expansion

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
