HyperWorks 12.0 Release Notes

Introduction
Altair HyperXtrude is a finite element solver for simulation of metal extrusion, polymer extrusion, metal
rolling, and friction stir welding processes. It has process specific features for each of these processes.

12.0 Release Notes - HyperXtrude for Metal Extrusion
Hensel-Spittel Constitutive Model
Hensel-Spittel model is implemented in HyperXtrude for modeling the workpiece. The Hensel-Spittel
model describes the flow stress as function of temperature, strain rate, and strain. Including the
dependency on strain improves the accuracy of flow stress calculation. Hence, the predicted results are
more accurate and agree well with experiments.
HyperXtrude now has four built-in constitutive models for workpiece:
• Sine Hyperbolic Inverse
• Metal Forming Power-law
• Norton-Hoff
• Hensel-Spittel models
Particle Traces using AcuPT
HyperXtrude can now create particle traces using AcuPT, which is part of AcuSolve software. In this
release, this feature is limited to steady state solution. Generated particle trace data will contain a
history of velocity, pressure, temperature, and strain for each particle.
Profile Shape Factor
Computes the shape factor and prints this data in an .out file.
Indirect Extrusion Results
Indirect extrusion module will now consider the shape factor of the profile in the friction calculations.
This enhancement will increase the accuracy of the results.
Tool Deflection Analysis
Support to export pressure loads from the material flow analysis in HMASCII format for use in the Tool
Deflection Wizard is implemented.
