ANSYS Workbench Tutorial: Static Analysis of a 3D Beam

Introduction

  • First video in the ANSYS tutorial series.
  • Focus: Familiarizing with ANSYS Workbench and workflow.
  • Problem: Bending of a 3D Beam with a monkey sitting on a wooden bar.

Problem Setup

  • Geometry:
    • Length of bar: 1 meter
    • Cross-section: 0.1 x 0.1 meters
    • Force applied by monkey: Uniformly distributed, approximated to 30,000 Pascals.
  • Material:
    • Material of the bar: Wood
    • Parameters needed: Young's modulus and Poisson's ratio.
    • Young's modulus for wood: 8 x 10^9 Pascals
    • Poisson's ratio: 0.3

ANSYS Workflow

  1. Select Type of Analysis
  2. Create Material
  3. Create Geometry
  4. Assign Material to Geometry
  5. Model Creation
    • Meshing
    • Set Boundary Conditions
  6. Solve the Problem
  7. View Results

Step-by-Step Guide

1. Launching ANSYS Workbench

  • Search for "Workbench" after installation to open the project page.
  • Set units to SI.
  • Select "Static Structural" and drag it to the project workspace.
  • Rename it to "Example 1".

2. Material Creation

  • Double click on the analysis type to open the Engineering Data tab.
  • ANSYS has a vast material database (e.g., structural steel, concrete, aluminum).
  • To create a new material:
    1. Click on Engineering Data Sources.
    2. Add wood by naming it and assigning properties.
    3. Set Young's modulus (8E9 Pascal) and Poisson's ratio (0.3).

3. Geometry Creation

  • Double click on Geometry to open Design Modeler.
  • Create a rectangle for cross-section:
    • Dimension it to 100 mm.
    • Pull the rectangle to a length of 1000 mm.
  • Create a partition for the monkey's area.

4. Model Creation

  • Double click on the Model tab to start the modeling process.
  • Assign Material:
    • Select the created wood material for the geometry.
  • Mesh Generation:
    • Generate a simple mesh or refine it using sizing options.
    • Change element size if required (default: 5E-2 meters).

5. Apply Boundary Conditions and Load

  • Fixed Support:
    • Fix one end of the bar.
  • Pressure Load:
    • Apply pressure on the partition area (30,000 Pascals).

6. Solve the Problem

  • Select desired results to view (e.g., total deformation, stress).
  • Click on the "Solve" button.

Results Interpretation

  • View total deformation and stress results.
  • Animation feature available to visualize deformation.
  • Use probe to analyze deformation at specific points.
