RD-HM-T: 1010 Cantilever Beam with Bolt Pretension

This tutorial demonstrates how to simulate a simple cantilever problem with a concentrated load at the free end, using Dynamic Relaxation (/DYREL) method to obtain a static solution.

In this lesson you will learn to:
  • Step 1: Load the model
  • Step 2: Create bolt connection
  • Step 3: Define material
  • Step 4: Define property
  • Step 5: Create contact
  • Step 6: Create boundary conditions
  • Step 7: Set loading
  • Step 8: Create time history output
  • Step 9: Create Engine setup
  • Step 10: Export and run model
  • Step 11: Check results

Model Description

  • UNITS: Length (mm), Time (ms), Mass (kg), Force (kN) and Stress (GPa)
  • Simulation time: [0 – 40.0 ms]
  • Steps to setup this model:
    • Fix the cantilever beam to the support with a 10 kN pre-tension. The bolt attains 10 kN in 10 ms and remains constant thereafter.
    • After pre-tension, a concentrated load of 0.72 kN is gradually applied at the free end of the beam from 10 ms to 40 ms and it remains constant thereafter.
  • Material used Elasto-plastic material /MAT/LAW2.
