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.



図 1.

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
1 x 10-5/°C
Remaining Area
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 45.51 1.098659635
