Benchmark Model
The 2-noded beam elements, Quad4 elements and Quad8 elements are used to build the model with 5 elements each for the coarse mesh and 10 elements each for the fine mesh. At time t=0, all temperature = zero and at time t>0, at one end temperature is zero and at the other end temperature is 100 sin(πt/40) °C. There is no heat flux perpendicular to the length of the beam.
The material properties are:
- Material Properties
- Value
- Conductivity
- 35.0 W/m°C
- Specific Heat
- 440.5 J/kg°C
- Density
- 7200 kg/m3
Linear Static Analysis Results
All results are normalized with the target value (36.60°C).
