RD-HM-T: 1040 Gasket

This tutorial demonstrates how to simulate a rubber gasket in sequential loading.

In this lesson you will learn to:
  • Step 1: Load the initial model
  • Step 2: Define material
  • Step 3: Define property
  • Step 4: Create rigid body
  • Step 5: Create boundary conditions
  • Step 6: Set loading
  • Step 7: Create time history output
  • Step 8: Create Engine setup
  • Step 9: Export solver deck and run model
  • Step 10: Check results

Model Description

The load sequence is:
  • Translation Transverse (10 mm)
  • Translation Longitudinal (5 mm)
  • Torsion (20 Degrees)
    Figure 1.

The model description is:
  • UNITS: Length (mm), Time (ms), Mass (kg), Force (kN) and Stress (GPa)
  • Simulation time:

    Engine [0 – 1.501] in steps of 0.5 ms for each load case

  • The outer circumference area is fixed on all degrees of freedom (VX, VY, VZ)
  • The center node is fixed on X direction and the X and Y rotation (VX, WX, Wy)
  • Gasket dimensions:
    • Thickness = 100 mm
    • External Diameter = 200 mm
    • Internal Diameter = 50 mm
  • Hyper-elastic material /MAT/LAW42 (OGDEN) (Rubber)
