RD-T: 3060 Three Point Bending
This tutorial demonstrates how to set up 3-point bending model with symmetric boundary conditions in Y direction.
- UNITS: Length (mm), Time (s), Mass (ton), Force (N) and Stress (MPa)
- Simulation time: in Engine file [0 - 6.601e-002 s]
- Only one half of the model is modeled because it is symmetric.
- The supports are totally fixed. An imposed velocity of 1000 mm/s is applied on the Impactor in the (-Z) direction
- Model size = 370mm x 46.5mm x 159mm
