RD-HWX-T: 1000 Tensile Test Setup

This tutorial demonstrates how to simulate an uniaxial tensile test using a standardized specimen with a defined cross-sectional area which is stretched until fracture.

The tensile test is a standardized method of material testing to determine the yield strength, tensile strength, elongation at break and other material parameters. It is one of the quasi-static, destructive test methods.

In this lesson you will learn to:
  • Step1: Load the Radioss (Block) interface and load initial solver deck
  • Step 2: Define material
  • Step 3: Define property
  • Step 4: Create rigid body
  • Step 5: Create boundary conditions
  • Step 6: Create imposed velocity
  • Step 7: Create output (time history / anim)
  • Step 8: Create Engine setup and export the model
  • Step 9: Run the model using Compute Console
  • Step 10: Post-process with HyperView and HyperGraph
