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.図 1.
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
