DEFORM
Metalforming simulation
Flexible yet process-orientated simulation system for large metal deformation
Compared to standard FEA and CFD codes, DEFORM offers significant benefits when simulating large deformation of metals and other materials, particularly if complex contact modelling and mesh rezoning (remeshing) may be required or microstructural changes are predicted to occur.

DEFORM can simulate forging, extrusion, rolling, drawing, spinning and any other hot, warm or cold manufacturing process involving large deformation. Results such as material strain and ductile fracture, die under or over fill, forming defects, press loads and tooling stresses are used to develop superior products and manufacturing processes
Bulk metal forming
DEFORM has been applied to hot and cold forging, extrusion and upsetting operations since 1980s, optimising the manufacture of products such as:
- Turbine disks
- Flanges and valve bodies
- Upset tubes and shafts
- Gears
- Crankshafts, connecting rods and pistons
- Control arms, tracks and yokes
- Bearings
- Medical implants
- Fasteners
Sheet metal forming
Sheet metal processes can be evaluated for splits, wrinkles, forming loads, tool failure and springback. Applications include:
- Drawing
- Deep drawing
- Bending
- Stamping
- Coining
- Blanking
- Ironing
- Pipe/tube forming
- Sheet forging
- Rubber pad forming
- Hydroforming
- Stretch forming
- Mechanical joining
- Roll forming
- Flowforming
Rolling
Standard rolling applications include cross wedge rolling, shape rolling, orbital forming and thread rolling. DEFORM can be used to optimise the rolled shape in the blocker or finished forging dies, typically resulting in a much higher material yield than traditional preforms.
Spinning & Ring Rolling
A specialised solver has been developed for ring rolling, spinning and other rotary forming applications to obtain accurate solutions within practical run-times.
Fracture
DEFORM can model the initiation and propagation of cracks due to ductile fracture. Punch-die clearances can be optimised for minimum roll-over and burr formation while maintaining low forming loads.
Die/Tool Life
Premature tool failures resulting from high forming pressures, inadequate die design or unbalanced interference fits can be analysed and eliminated using the coupled die stress analysis capability.
Productivity Tools for Engineers as well as Dedicated Analysts
DEFORM FORMING EXPRESS (2D / 3D) is the ideal solution for small to mid-sized companies looking to incorporate simulation into their design workflows. It is a practical and efficient tool for designers and engineers to predict material flow in cold forming and hot forging operations without the cost and delay of shop trials.
Simple to use, with Wizard-driven templates, it is still based on the renowned DEFORM calculation engine for high accuracy and fast results.
