Material data management Seventy percent of materials data becomes lost and unavailable to future projects. This results in time-consuming and expensive re-tests to obtain the necessary data for new designs. Design knowledge must instead be captured and managed for reuse. The Web allows this knowledge to be shared globally, supporting the Design Anywhere, Build Anywhere business climate (Figure 1).

Material data plus methods Moving from a simple database concept to a data plus methods base. Many teams within a company for example, manufacturing, design and engineering all have the basic need for materials data. Each team will certainly require unique views and interpretations of the same data. The benefits are clear, in moving up the progression from data management towards information and knowledge management (Figure 2).

Benefits of Material Database System (MDM) Benefits of material data bases need for traceability has been a key driver for many commercial materials data management projects Increase collaboration between your engineering teams by providing easy access to updated materials information. Save time and money otherwise spent on re-testing by allowing you to retain and re-use corporate materials knowledge. Make better materials selection decisions by providing web-based access to the powerful querying and data manipulation capabilities of a MDM system. Definition of different views of the same data, to reflect the needs of users in different functions or manufacturing teams. Provides access control by user or by group, even to different subsets of the same databank. April 2008 Autosim Birmingham 4
Interfaces between MDM and SDM 1. Interfaces to material data bases Which material data must be available for the simulation engineer? Which material data bases must be connected to a simulation data management system? Which material data are interesting for the simulation engineer at which point of time? Which material data bases could be merged? How could be reduced the number of material data bases for each OEM at supplier site? How could be reduced the number of material data sets for each unit system, solver and OEM? 2. Handling of connecting links How can be handled connecting links in simulation data management systems? How can be replaced connecting links through mathematical models for the specific simulation task automatically? April 2008 Autosim Birmingham 5
Interfaces between MDM and SDM 3. Material models Which material models must be provided for the simulation task? Which load case needs which material model? Failure / Fracture / Damage - most materials across all load cases; understanding the differences and how to best model them in CAE, choice of parameters, etc. (Knowledge Based Engineering) Usage of individual material models, with non-standard description (e.g. user_mat functions to link self-developed material models) and integrate them easily in the applications. April 2008 Autosim Birmingham 6
Interfaces between MDM and SDM 4. Manufacturing Simulation Simulation of material parameters, e.g. in injection processes, the orientation of the fibers are calculated which influence the global behavior of the resulting material. Consideration of manufacturing effects (e.g. deep drawing of sheet metal) for crash / endurance strength simulation. Example: Differences in the thickness of sheet metal parts caused by manufacturing process can decline the simulation results. Example: Consideration of special heat influence areas caused by alloy welding. 5. Knowledge based engineering Assignment of material models (Selection of the right mathematical formulations of the material model for the used simulation load case). April 2008 Autosim Birmingham 7
Interfaces between MDM and SDM 6. Simulation data management (SDM) Deployment of country specific material interdictions. Must deliver it the information, which materials are allowed to be used in the development project? Material data must be provided in the SDM system? Design changes in PDM system must be communicated to simulation engineer by SDM system. Example: Designer changed the window pane to an infrared beam adsorbing window pane. Therefore the simulation engineer must change his concept of air-conditioning. April 2008 Autosim Birmingham 8
