This tutorial demonstrates how to set up a 3-point bending model consisting of a head
profile and a closing plate.
This validation test is a common test to determine the bending strength during
bending load. The usage of the head profile structures is a common design feature in
automotive and aero industry. Figure 1.
In this lesson you will learn to:
Step 1: Import Solverdeck
Step 2: Check /BEGIN card
Step 3: Define material
Step 4: Assign material
Step 5: Define property
Step 6: Assign property
Step 7: Create solid spotweld
Step 8: Define failure /FAIL/CONNECT
Step 9: Define rigid body
Step 10: Create boundary condition
Step 11: Create imposed velocity
Step 12: Set contact
Step 13: Define output (time history / anim)
Step 14: Create Engine setup and export the model
Step 15: Run the model and check the results in HyperView and HyperGraph
Model Description
The model set up consists of:
Material creation (with strain curve creation) and assignment:
Elasto-plastic material /MAT/LAW36 (plastic):
[Rho_I] Initial density = 7.85e-09 (ton/mm3)
[nu] Poisson’s ratio = 0.29
[E] Young’s modulus = 210000 (Mpa)
UNITS: Length (mm), Time (s), Mass (t)
Simulation time: [0 – 7.01E-02]
Boundary Conditions: The supports are all fixed. An imposed velocity of
1000.0 mm/s is applied on the impactor.
Model size: 370mm x 46.5mm x 159mm
Prerequisites
