In the following picture, the die entry radius in the addendum region should disappear smoothly in a flat surface (or infinite radius). In current version, there is no function to directly fulfill this need.

Sometimes the car coordinate system is not available with the stamped part. So if one wants to map stamp results, to an assembly operation, first of all the part needs to be transformed to the right position.

If you need insight on the restraining force of a geometrical drawbead or want to know the transmitted force in a sheet or tube section, you can define a force gauge.

During a project the need to visualize the functionality in 3D arose and some 3D symbols were created, which are now made available as a goody.

Major automotive companies spend a lot of money to describe all materials used in their simulation processes. To ensure simulation quality also at supplier sites, they want to give the material data sets to them, but not for free. One half of the solution is...

For a comparison of the virtual stamped part and the nominal CATIA V5 part one can use PAM-STAMP, or go back to CATIA. Since the meshed part is not easily converted into surfaces again, one solution is to use an overlay of the CAD part and of a VRML export of...

Porosity in castings is a major defect since it affects the mechanical properties. In particular porosities are sites for the initiation of fatigue cracks. Therefore, the reduction of porosity fraction and size, the control of porosity distribution and...

In case there are no measured material data for simulation purposes, it is possible to determine hardening curve from information usually provided by material supplier.

Sometimes only rst files there are available and dependent pre file of an intermediate stage setup (lost data, picking with a process variant, …), which is not possible to run in another PAM-STAMP version, usually in newer version. It is possible to create a...

A dimensionless quantity is a quantity without any physical units. Such a number is typically defi ned as a product or ratio of quantities which do have units, in such a way that all units cancel. Dimensionless quantities are widely used in the fields of...

Successfully modeling solidification of Cast Iron is of great help for the foundries to reduce their production costs and thus to increase their profits. If the basic physical solidification phenomena are correctly modeled by the simulation tools mold...

Two application examples are showing new possibilities to take into account stress and deformation by the simulation of continuous casting processes. The variability of the presented examples prove that the proposed method is not limited to a certain class of...

Casting process issues related to hot tearing and cracking of the casting, thermal fatigue of dies and prediction of the final shape of a part are a challenge for foundries. Powerful, multi-physics simulation tools are now available to address them. This e...

Foundries that have implemented casting simulation to shorten development time, further wish to use simulation in order to reduce the cost of subsequent processing steps. This often requires the simulation of heat treatment.

ESI group needs to license, manage and track a variety of licensing options, platform and product dependencies. FLEXlm is one of the only software that is up to this task. A simple, shrinkwrapped license management product would not be powerful and flexible...

Reduce part development lead-times by a better knowledge of process and an early confi rmation of metallurgical capabilities is one of the main topics for investment casting technology. Numerical simulation is one of the major tools which can be used to face...

The manufacturing of iron, steel and non-ferrous castings is achieved using a variety of casting process designs, and most of these involve the use of sand cores which form the internal shape of the casting. A good quality casting requires a good quality core...

“To pull a bigger wagon, it is easier to add more horses than to grow a gigantic horse.” This paraphrased quotation nicely expresses the basic concept of parallel processing. The speed of sequential computers has been doubling every eighteen months, according...

Passenger safety in cars, planes and other transportation vehicles is an ethical obligation, a legal issue and a technological challenge. Simulation is a well implemented tool in order to test the behaviour of a car body during crash. The models, including...

Optimization is becoming a very popular word. However, what does it mean and what does it involve? The goal of this e-tip is to give some keys about optimization concepts and its use in process optimization. In a first stage, we will describe the type of...
