Define the primary pressing direction along a major axis (typically the ).

If the steps become infinitely small and fail to converge, check your friction factors or step size. Drastically changing velocities or tight contact tolerances often cause convergence lockups.

In the Simulation Control window, set simulation parameters:

Before running the simulation, you must define the spatial relationships between objects. DEFORM-3D offers several positioning tools:

Compare simulation results with a physical, simple test case (e.g., cylinder compression) to validate your material model.

Whether you are a manufacturing engineer looking to optimize a forging die, a student writing a thesis on grain flow, or a machinist wanting to understand why your parts crack, this will take you from zero to a functional simulation.

DEFORM-3D is a powerful finite element method (FEM) simulation system used to analyze bulk metal forming, heat treatment, and machining processes. It allows engineers to predict material flow, temperature distribution, tool stresses, and potential defects without costly physical trials.

Choose and set the value to 0.3 for hot forging. Do the same for the Bottom Die and Workpiece . Step 8: Run the Simulation Click on Simulation Controls . Set the number of steps to 100 . Set the step increment to 0.01 seconds . Save the database. Open the Simulation Engine and click Run . 📊 Analyzing Your Results

Set the to Shear Constant (preferred for hot bulk forming). Input a friction coefficient (

Monitor the step log. Look for the . If it stays consistently below 0.05, your simulation is mathematically stable. Phase 4: Post-Processor Evaluation and Analysis

Close the Pre-Processor and return to the main DEFORM dashboard. Select your project database file. Click the (or Simulation Engine) button.

Select the and ensure its velocity is set to 0 across all axes (fixed tool). Step 6: Inter-Object Relations (Friction and Heat Transfer) Define how the surfaces interact when they smash together. Open the Inter-Object Relations matrix.

For advanced users, DEFORM-3D can simulate grain growth, recrystallization, and phase transformations during hot working and heat treatment. This is crucial for applications where final mechanical properties are directly tied to microstructure.

Introduction to DEFORM-3D

Every simulation in DEFORM 3D follows a structured, three-stage pipeline. Understanding this flow is essential for troubleshooting and ensuring accurate results.

Objects that apply force but do not deform. Classifying tools as rigid drastically reduces computation time while keeping contact stress calculations accurate.
