Infoday ENVYO and Composite Analysis




Nowadays, the words “industry 4.0”, “process chain” and “mapping” are often used in industrial research and development environments and point out the need to make use of simulation and experimental data for further numerical analysis. Within the DYNAmore Company, this topic is being targeted within a number of industry and research projects and as a result, the software tool ENVYO® was introduced to the public at last year’s LS-DYNA User’s meeting in Bamberg, GER. Thereby, a detailed introduction to the application possibilities of this tool to close the simulation process chain for components from metal forming applications, as well as short and continuous fiber reinforced composites was given. ENVYO® perfectly fits into the number of products accompanying LS-DYNA since it defines links between different tools for process simulations and the structural analysis with LS-DYNA and allows the user to process and homogenize those simulation data in many ways. In some cases, the tool can also be used to for the post-processing of a huge number of simulation data. ENVYO® allows to consider a large number of material models and corresponding history variables along the simulation process chain and therefore helps to fully close it completely.

On this information day, experts from industry and research will report their experience from the various application possibilities with the software tool ENVYO® to the public. Together with the information exchange with the early adopters of this technology, attendees will have the chance to get information about the newest implementations within the ENVYO® software and to directly discuss their needs with the developer of the tool. This will help to push the software solution to fully close the simulation process chain for a large number of applications.


Composite Analysis


Due to the increasing importance of lightweight construction, where the aim is not only to economize on weight but also to improve rigidity and strength, the use of composite materials has increased dramatically over recent years. If considerations are made regarding the use of such materials for crash-relevant components, the requirements of simulation tools increase enormously - especially in automotive construction. As a consequence, numerous enhancements have been implemented in LS-DYNA.


The aim of this information day is to inform participants about the state of the art in simulating composite materials. In particular, an overview of existing options in LS-DYNA for simulating composite materials is given and current developments will also be discussed. Furthermore, new features in tools increasing the usability of these materials within LS-DYNA are presented (ENVYO, LS-PrePost). Presentations from both, research and industrial partners will illustrate the wide range of simulation approaches for fiber reinforced composite materials from a practical point of view. Furthermore, there is time for discussion and exchange between the software developers and other LS-DYNA users.
